It'd never work for a variety of reasons.
The chief reason being that it's no longer an "Attitude Era" type of society these days. We live in an age where political correctness has become a religion almost unto itself. Don't get me wrong, I'm personally glad to see some outdated and prejudicial ways of thinking finally being pushed out of the way. The problem is that I believe that political correctness is being pushed to an absurd level because it's gotten to where EVERYTHING is being made into a federal case. You can't say or do anything these days without someone going to Facebook, Instagram Twitter, YouTube or whatever getting upset about it. For instance, say somebody overhears you making an offhand, joking comment about someone wearing a nice suit, immaculately groomed and is obviously of Italian descent is speaking heatedly to someone else on the sidewalk in which you say "I wonder if he's making him an offer he can't refuse." You know, a reference to The Godfather movies. Seriously, someone can stretch that joking comment to such a degree that they consider it an ethnic slur by taking the position of "Oh, so just because an Italian guy dresses nicely and has money, it must mean he's in the mafia." Sometimes, a joke is simply a joke like a rose can be just a rose. There doesn't always have to be some underlying metaphor about everything, that it always has to have some deeper or ulterior meaning under the surface.
Look how bent out of shape people got during the early days of Jack Swagger & Zeb Coulter's "Real Americans" gimmick. People got all torn up because of CM Punk & Paul Heyman "mocking" Jerry Lawler having a heart attack or "disrespecting" the memory of Paul Bearer during the build of Punk's match with Taker at WrestleMania 29. Not long ago, people were criticizing WWE for the Rusev & Lana characters after the plane was shot down in the Ukraine even though the gimmick had previously been going on for several months, long before that tragedy took place.
As far as a "mature themed ppv" goes, it's really sort of ridiculous because "extreme violence" is no longer particularly fashionable in pro wrestling. After all, look at the number of wrestlers who've dropped dead over the course of the past 15 years at young ages. Many of them have died as a result of overdoses of painkillers because their bodies have been so racked with injuries from putting themselves through the hells of "extreme violence" matches over the course of their careers. A lot of wrestlers who're still around who did all the hardcore stuff are suffering the consequences now as they're older. Just take a look at Mick Foley as the only real example you need for that, except Foley was lucky in the sense that he managed to make it into the WWE and make a lot of money. There've been plenty of wrestlers over the years out on the indie scene, wrestling in Japan, Europe, etc. who did the hardcore stuff and they don't have a pot to piss in and could hardly muster the strength to limp over to the pot to piss in it even if they had it.
The negative consequences of wrestlers dying at young ages due, in part, to the damage they'd done to their bodies as wrestlers, especially in light of what happened with Chris Benoit, gained national media attention. Essentially, WWE didn't give a crap what wrestlers were doing, what they put into their bodies or what they did outside the ring as long as it didn't affect their job. When Congress stated it was considering stepping in and regulating WWE, which would essentially take control of the company from Vince, thereby being made Congress' bitch, Vince knew he had to change things not only because it was the right thing to do, but for the sake of business. It's the reason why there are no longer shots with steel chairs to the head, why wrestlers are no longer slammed on top of beds of thumbtacks, why piledrivers aren't used in WWE, etc.
As far as blood goes, I didn't really consider how dangerous it could be for wrestlers to blade during matches. Sometimes, accidents happen in a match to cause someone to bleed, that's just how it is and it's part of the risk a wrestler takes. However, the problem with bleeding is that it's an excellent way to spread viral diseases. In 2007, indie wrestler Devon Nicholson contracted Hepatitis C after wrestling Abdullah the Butcher. Abdullah had the disease for years, didn't inform anyone, he bled all over this kid and transmitted it to him. Earlier this year, he won a $2.3 million lawsuit against Abdullah and the whole thing essentially derailed Nicholson's wrestling career. At the time this happened, Nicholson had signed a deal with WWE but the deal was rescinded after it was discovered Nicholson had contracted Hep C. Reports have said that Nicholson is finally cured, which has taken 7 years of intense treatment. Back in 2005, Bob Orton, Jr. was part of Randy Orton's feud with The Undertaker and at Armageddon 2005, he bled all over Taker and Orton had contracted Hep C as a teenager. Taker was unaware of it, though he found out afterward and flipped out. Orton was fired soon after and alleges that he told Big Johnny about it prior to the match and was told to do it anyhow whereas Big Johnny denies it. Taker got lucky there and managed to avoid infection. It's common knowledge that a lot of wrestlers sleep around, and Hep C can be classified as an STD. Just like HIV, it can be spread through sexual contact or through blood. It's not as if WWE can run blood tests on every single wrestler every single day. In some places, a single blood test can run very high, depending on the test and specifics you want discovered. Even if they could do tests on every single wrestler, which is about 100 for male & female wrestlers, every single day, they'd be out millions of dollars each year.
