Sure; I presume he cannot keep the Mirror of Possibilities?

Edit: I can also remove the Space-Time Jutsu.

He can keep the mirror, I like the concept of his multiversal abilities. He's a Jounin so he should be powerful. I think you should remove his access to the Sharingan and Byakugan though.

He can keep space-time, since it's his ability theme.
