The problem wasn't so much 3D itself as much as it was texture mapped 3D, both of which struggled with that (the Jaguar less so than the 32X in that regard). Unfortunately, non-texture mapped 3D was dated pretty quickly, on one hand thanks to the 3DO that was already on the market, but especially once the PS1 and Saturn dropped. The flat (32X) or Gouraud (Jaguar) shaded polygons weren't going to cut it then.
As far as what a Mortal Kombat would have looked like on the Jaguar, all you have to do is take a look at Kasumi Ninja. As poor of a game as it is, it at least features the same kind of large digitized sprites, smooth framerate, high color count and the same scrolling floor effect. Had MKII in particular been commissioned, it's possible it may have been one of the better conversions at the time.
