Yea, that should be fine. If you really wanna get crazy, imagine making the bottom flat (misses the ring gear) and shave it that way. The way I speak of eliminate the plug but keeps the general rounded shape. The flat makes it look like you took a bandsaw to it and then welded on flat plate.
I did the plug-eliminator this time, and maybe I'll do round-eliminator down the road... Who knows...
4crawler makes the plate precut and comes with a template for shaving the diff if you want to go that route
