I don't see it happening for two reasons: First, taking the time to completely reskin or change the artstyle of the game would take too much time and resources in the eyes of the publishers, and they could easily just release them on PS4/XBone as special editions. Second, most of western titles have as a selling point how hyperrealistic they look, and people buy them for that. People who try to avoid games that look cartoony will just keep ignoring the system.
WiiU won't make a turnaround, at least not for western developers. If Nintendo made extra effords in Japan (Youkai Watch U, Final Fantasy, Dragon Quest, Monster Hunter U), they could expand their userbase with fans of those kind of games, but there's no hope now for the FIFA-CoD-AC-Battlefield audience to pick up a WiiU. Better luck with that on the NX.
