He should still be able to use kamui because's unlike kakashi... the power does not come from obito's eye, but within him... just like every other uchiha's powers...
But, I think obito does not have the body to use the RG's full potential which is why obito has not used but one RG jutsu... Still though, using his own jutsu with the RG (because it is just a higher form of the MS) should be no problem...
Probably because Madara unlocked the RG for his own eyes, Obito was taking someone else's eyes and switching his out
