Imagine Uchiha Obito with both his Sharingan...

[Angelic.]

obito was definatly handicapped by only having one eye. he wouldnt be scared of no itachi lol

I can't see anyone beating him if he had both.

Could he ever have a susanoo or use amaterasu?

Are you saying itachi cant last five minutes against obito?

He will troll Itachi so hard with double Kamui. Sucks himself in the blink of an eye. Also can suck Itachi into Kamui dimension that Itachi will not have time to react. Maybe, only a person with FTG can run away.
