Ficus grafting conflict species?

[Jason_mazzy]

Does anyone know of any grafting conflicts in ficus?

I am thinking nerifolia on a tigerbark (retusa) that I have been working.

I wouldn't do it. There's too great of a difference in bark.

I think It'd be a fun project to do if you have a shit tree you don't mind practicing on. Ryan does make a valid point with the bark differences though.
