I don't see this as being feasible in ANY form, for the simple fact that TNA envisions itself as an up and coming OPPOSITION to vince's wwe. First off, Hogan doesnt have THAT MUCH PULL in TNA where he can sell the company to vince.. thats ludicrous and an idiotic thought to begin with.
Dixie has put too much work and money into TNA to do something stupid like sign over the rights to the federation to hogan.. and say what you like about Dixie.. she is NOT a stupid woman.
Hogan will use the federation to push his book or movie or whatever it is that he's got coming out, and after a few months, he will ride off into the sunset again... tho I am laying odds with a reign as TNA World Champion on his resume.
If the day comes where TNA closes its doors and ceases production, I dont think there will be ANY amount of time afterwards where they will sell their video library or whatnot to vince.
TNA was created as an ALTERNATIVE to vinces product, so why would you even consider selling the rights to your video library to the man? And before you all jump on me saying that "I bet WCW thought the same thing and look what happened to them." let me point out that WCW was a sinking ship that was looking to patch holes at the time that the NWO showed up.
If it werent for the 'shot in the arm' that the promotion got from that angle, then Vince would have owned them a LOT sooner... that, and the fact that "Billionaire Ted" pretty much 'screwed the pooch' when he pulled out of the company. With Ted's money behind them, WCW had a chance.. a VERY GOOD CHANCE... of burying Vince McMahon, but like the true predator that he is, Vince bided his time until even AOL etc pulled out from WCW and left it in a death spiral. Vince swooped in and bought the ENTIRE franchise.. titles, wrestlers, name, copyrights, images, video library etc for a mere 2 million dollars.
Since then, there hasnt been an alternative to vince's wrestling machine, but Dixie and TNA are giving it their best shot.. and since they are what.. 7 or 8 years into thier own fed now.. selling everything to Vince would be a stupid business decision.
I could see Dixie holding onto the rights to all tna's properties.. images, wrestler names, videos, etc.. either that or selling them to IWGP or some other american fed, like maybe NWA or something.. but NEVER to vince
