You're really, really, really, really stretching the word "legend" here when it comes to most of those guys.
Jeff Hardy is the only real star among them and he's signed with TNA. In spite of the storyline going on in which Hardy "left", he's just been written off television because he can't go on the UK tour because he won't be allowed a work visa in the UK due to his past legal trouble. Matt Hardy will always be viewed as the lesser Hardy and any real success he attained in WWE was due to riding his brother's coattails. Besides, he's probably burned a lot of bridges in WWE the past few years with all those ranting internet videos he's put out.
Val Venis, Savio Vega, Ahmed Johnson, Taka Michinoku, Bart Gunn, Bob Holly, D-Lo Brown & Droz were all HIGHLY forgettable, primarily lower mid-card guys that 99% of viewers won't care about, remember or even know who they are. Droz certainly isn't a legend and the fact that his single most memorable moment in his wrestling career was the night he was paralyzed isn't exactly something to celebrate. To make matters even more awkward, D-Lo Brown's most memorable moment in his career is simply being the guy who paralyzed Droz.
As for Ken Shamrock, he got into the WWE based on his success in MMA when he was still a respected MMA fighter with a good record. Now, he's an over the hill 48 year old man that's tarnished his own MMA legacy by fighting much longer than he should have. When he left WWE and went back to MMA, he fought a total of 15 fights, 10 of which he lost. A while back, he did an interview saying that he wanted to come back to WWE but WWE's not interested. He then did a little bit of a shoot interview that's just using the same old formula: painting himself as the hero in the story, saying that this guy didn't like him or that guy didn't like him, that this guy's ego was out of control, that he should have been main eventing and exaggerating his contributions to the company to a pretty generous degree.
As for Jim Cornette, there's too much bad blood there. Which if what I've heard is true, Jim Cornette seems to have bad blood with just about everybody these days. Again, if all the various reports are true, Cornette basically thinks wrestling companies should still operate as if it was still 1980.
As for Lex Luger, meh, couldn't care less. I was never a fan of Luger and thought he was pretty overrated.
I'm sure Jeff Hardy will be looked at as legendary, mostly for his time as a tag team wrestler, as his success in the late 90s through the mid 2000s overshadows anything he's done. Jim Cornette was a great manager and fits the bill of a legend. Even though I think he's pretty overrated in terms of ability, Luger was a big star and he'd probably qualify as having a legendary career. But as for the others listed? Nobody's gonna care. If you want legends that people will recognize and actually want to see, then get actual legends like some of those on Raw this past Monday. In addition, bring wrestlers that fans haven't seen in a long time like Harley Race, Terry Funk, Demolition, Gerald Brisco, Tully Blanchard, Barry Windham, Kevin Von Erich, Road Warrior Animal, The Midnight Express, Larry Zybyzko, Larry Hennig, include some legendary commentators like Jim Ross & Lance Russell, maybe bring in Jim Crockett, Jr. as he's one of the last of the old NWA promoters still around.
