Good idea - could just hack a transaxle for a compact diff?
or take one from any small rwd/awd vehicle with workable output flanges, they're pretty compact already and setup to go in in a 'T' configuration. I would think that would take up the least amount of precious passenger compartment.
Considering that others are suggesting making a custom-built oil bath for the chain drive, I'd think the diff starts looking better.

Just within this last week, I had a simlar idea pop into my head for my 98 Civic Cx. I'm glad to see that someone else was way ahead of me with proof of concept because until now, I just thought that this was an idea that had only existed in my mind.
This is link is now closed; but I would love to know exactly how this guy hybridized his Ford Aspire . Would you by chance have saved the posting? If not, I think that we should all revisit this topic so as to make another prototype a version reality. I'm game to be the guinea pig, so let see if we can all put our heads together on this.
