using double overdrives with a cummins

I have been reading a lot of threads about cummins conversion and the subsequent gear changes people are doing to get the rpms down.

Has any one tried this combo:
cummins ->o/d tranny ->transfer case->gear vendors over drive unit?

as long as your not in four wheel drive with the O/D activated it seems like that could drop the rpms quite a bit.
