I would like a reinvented feast or fired match, that is a hybrid of FOF and MITB, as in a 4 way ladder match with 3 cases, in each is a contract for a title shot for one of TNA's 3 singles titles, so theres an X Title shot, TV Title Shot and World Title shot, and whoever fails to capture a briefcase is the one who gets fired.
This imo makes FOF more interesting as you reduced the number from 20 guys who 70% of them are a cluster of guys you have no purpose for, instead it's 4 upper midcarder's and also when it's down to the final 2 it increase the intensity of the match as there's a sudden must win aspect, also get rid ofd the gameshow aspect of the revealing of the title shots and trading of the cases instead once the match is over you just have the 3 guys open the cases up themselvess.
IMO doing this would greatly improve the concept as it's more serious and therefor more important, the way TNA had it treated the entire concept like a joke, plus Pole matches suck and are far to com,edic in general where as a Ladder match feels more important and selling it as a dangerous match isw much easier to do.
