sorry my bad I thought you meant it the other way around, I was not aware the C4 was this way, not that I really looked.
I am not a big fan of driveshafts being load bearing even though many designs have had good success eg the jags (it's just a me thing)
remember this is a mid engine, transaxle is mated directly to rear of engine and as such it sits between the rear wheels already.
transaxle will at most be supported at rear end directly by chassis subframe, at the front by the engine itself which is chassis supported on it's mounts.
driveshafts then will couple directly to transaxle with appropriate adapters.
wishbones will be attached to chassis subframe.
