Um... I have. Plenty of times. I made a Jigglypuff with Sonic spikes, and a Dr. Mario with no Stethoscope or Headband (sorry, I'm in no position to provide snapshots).
Now, I actually have, a flawless vert importer for Melee, on my site. On the downloads page, there is a GM program called 'Melee Model Converter'. Now, read the instructions for this one, because it's not as friendly as the CPP program. However, it will not glitch. It will export the vertices within a 1/256^2 byte. However, I can't remember, this may be the one that doesn't export for extremely hi-def models (only Toys are hi-def from my experience). Anyway, just look and see.
Downloaded, Milun. Glad you think the texture fits.
(Hm. I wonder if a semi-64 MK is possible... Remove the middle, keep the left/right, move some blocks... Huh.)
