Nope, another version of the character would be sought out. There is one way to get out, however. Not to decline Jonathan's orders, but to ignore them. Ignore him. In the first lessons he gave you, one was that your mind is one of the most powerful tools you have. Deny his existence to you, and away he goes. Though, of course, you're missing out on a chance at godhood. And who doesn't want to be a god?
Chrysea could bring back her people and save the multiverse (and Bennett). Ciana, her sanity. Mikel could resurrect his family. Nima could... do whatever the hell it is zile wants to do. All achievable with Simultaneous.
And in case any of you are wondering, Convergence is next set of orders.
