Honestly, I don't think that any combination of these would be good. What most gamers (including me...) want out of a game is something innovative and new, something that makes the game stand out from the others. This is why Pokemon became so popular when it came out. It gave a unique taste to the gaming community back then, and made capabilities of video gaming more noticable. So I really think that making another Pokemon game, without having some fresh ideas put into it, would be a bad game overall.
