Well, they'll speed things up somewhat.

Yep.

AC3D does too...and SSG doesn't care.

Well, you don't need 24 vertices - 16 is enough if
you build it with two triangle strips.

The current ssgVtxTable comes pretty close to storing
the data you need for CVA's - so deriving a CVA class
from it should be really easy.
