Definitely no chance we'll ever see that in an official game, TPC/GF hates work, and just slapping them all into one game would be total chaos.
Plus, we're never going to see games reuse old gimmicks, no matter how much people like/dislike them, TPC/GF seem to really want each gen to have a new gimmick and toss the old ones every new gen, even if the previous gimmick was one or two patches away from being good.
