Could an heir of mind theoretically become a hivemind of all the versions of them and their minds across paradox space/timelines?

I’ve argued the Lord/Muse of Time to do something like this- For just like, multiple people in general. But for all of THEIR versions? That could be an interesting take on it, yes. Terezi, as a Seer, was also kind of close to doing this, I should point out.
