Anyone look at an XJ cherokee rear end for a BBP conversion?

Not well versed in this subject other than Rick Eherenburg suggested this swap. On one of my junkyard crawls I dove under a bunch of grand Cherokee’s. The pinion gear shaft looks small and weak. Not sure if they were the right axles though. Probably stand up to a /6 or a stock 2 barrel v8.

Disc brakes and an aluminum center section case where its desirable points.
