Nintendo will want a style that's distinct and which works for DK. Personally, I think Tropical Freeze had that and it could be adapted into a largely linear 2D/3D hybrid game - not dissimilar to Crash, but faster and with more destructable environments, really. Maybe it'll be more like 3D World in that it'll be primarily linear, but otherwise I'm not sure if the comparison would pan out.
But ultimately I don't see Nintendo bringing DK in-house just to ape another existing game from a different franchise (pun intended). What they do has to make sense for DK as a character and as a series.
DKC in 3D has been made.
It's called Crash Bandicoot :)
