I've listed out this plan a dozen times before but i'll do it again.
Back in the mid to late 90s, WWF ran a series of PPVs known as In Your House. For the most part they were two hours shows with a slightly lower level main event usually still for the title. The cost was dropped from $30 to $20 which made sense as it was 2/3 of the usual run time. Your main event might consist of the world champion defending against a glorifed mid carder. Picture this is you will.
Imagine if Judgement Day was one of these events. Based on MVP suddenly being pushed to the main event scene for all of two days, we'll go with him. Instead of having Orton/MVP on Raw that night, build MVP up as Orton's first challenger. He faces Priceless in singles matches for two weeks then pins Orton in a 6 man or something the week before JD. At the PPV, they have a 20-25 minute match where MVP comes so close to winning but ultimately falls short. Let's look at what this accomplishes:
MVP gets a taste of the main event. He's not ready to make that leap yet, but people see him headlining a PPV, he gets to show what he can do there, and he gets put over while still losing.
Orton looks good. He beats the US Champion, someone he should beat, has a good match doing it, and has a successful title defense on PPV.
Most importantly, it lets you build up Orton vs. Batista as a big time match. Instead of giving us a three week build up, using this you could build it up all the way to Summerslam if you tried hard enough. At that point, the feud is huge and we get the epic main event showdown that's been brewing for 5 months.
Also, if you drop the price down to say 25 dollars, while you lose the initial 15 dollars, how many more people would order a show that's almost at half price? There are likely some fans out there that simply can't afford to buy two shows such as Backlash and JD back to back so they would have to pick one or the other, meaning the company only makes 40 dollars for two shows. If you lower both shows to 25, there's a good chance the customer can afford the extra ten dollars rather than 30 dollars, meaning the company brings in 50 dollars instead of 40, meaning they make more money.
You can keep the number of PPVs, just alter how they're made and sold.
