Tekken Vs VF (never gonna happen)

Just a random thought as I was wandering through a couple of arcades, and had spent some time playing Capcom Vs. SNK. Why, I thought to myself, are there no (excluding megamix) 3D "Vs" fighting games?

Tekken Vs. VF would be sorta cool... of course you'd have to be able to choose which system to use, etc., but man it would be satisfying to spank Paul with Akira

 

there was a thread on TZ about this a while back ....
no way cause T4 paul is WAY easier that VF4 akira from everything i've heard.
of course, pai vs ling, lei vs lei, wolf vs king, marduk vs vanessa ... oh you all know ...
