That's actually a really solid scenario. I'd enjoy that. Joe Park is the best part about TNA right now from an entertaining standpoint, but removing that to make the payoff for Aces & Eights worth it would be a fair trade. Good idea.
Me too. I remember back in the 90s when Peter David was writing The Incredible Hulk he really pushed the Multiple Personality angle. We had a run of issues where we had a mindless, furious green Hulk, then a run of issues where we had a cruel, cunning (but weaker) grey Hulk. Finally, these two personalities were merged with Banner's personality which resulted in an intelligent (Banner), cunning (grey), strong (Green) Hulk. And these issues were kick-ass.
A similar scenario could result in a "feel-no-pain" Hardcore, monster Abyss, but with Park's intelligence and cunning (i.e very much like Bane). It would freshen up the Abyss character and he could still flip-flop between Joseph Park and the old Abyss at times. too, if necessary.
I'm not into the Aces and 8s angle, but I would enjoy that. Anything else I can think of (Bischoff, Jarrett etc) would be so underwhelming after all of this build-up, it would be like being kicked in the nuts.
