If you did it would just leak out of the diff locking pin holes. The locking pins go threw the diff cup and into the spider gear on that side when the locker is engaged. So you basically have to choose between grease filled diff and locked diff. I think I'll stick with silicone oil filled sealed diffs, I'm sure I could get a pretty damn good compromise with the right weight oil that nobody would really notice the difference.
