In the vein of DK64? I'd take a waggle-free DKCR2 with shameless nostalgia exploitation and the ability to choose from several different characters (Donkey, Diddy, and Dixie at the least) over that.
I did love DKCR, it's actually one of my favourite 2D platformers, but I've always prefered 3D platformers/adventure games. DK64 wasn't perfect, but it was a fun game and with some improvement, could be very cool (Banjo-Kazooie was definitely a better example of a 3D adventure game). Imagine a Mario Sunshine-like game but without the FLUD gimmick and set in the Donkey Kong universe.
Plus I still think a DKCR game on 3DS is possible.
