almost, the modern front wheel drive already has a transaxle. the differential is incorporated into the transmission housing, already saving weight and space.

I'm also reminded of the Acura SH-AWD which has planetary gear sets on each axle in their Rear diff. so they can overspin the outside wheel which pulls the car around turns.
