Well I've thought about that (i.e. big left side internals into small housing), but I seriously doubt that it'll be easy.
The internals can be bought in either a small (135mm) or a big (165mm) version, so that's probably for a good reason.
If I were to mod it, it would have to be spot on, so the mirror glass would fit exactly in the center of the housing, any rubbing and it would pop off after a big bump.
I think I'll go for a powered one on the left (small) and a manual one on the right. Sounds naff, but I've already got the right manual one, so that's why. I consider it 'Out of the box thinking'.
