Alliedassault - STG44 sound/texture/model mod

Before I bug weapon "mod-master" Leon again with another bothersome email, I thought I'd run it by you guys first...

I'm trying to create a sound/texture/model mod for the STG44. I have photoshop 7, scorpio's MoHAA exporter, and a 30 day trial version of milkshape. I already have the new sounds for the mod - that was the easy part. Now I'm trying to import a gun model from SOF2.

Now, I've heard it's possible to import models from other Q3 based games with scorpio's exporter. But I've also heard other modders say it's not. Does anybody know?
