is an r316100 world/kernel possible from a r314700 jail?

[Chris H]

While I *know* this at *least* risky business;
I was wondering what the chances are that I can create
a new world/kernel from my current custom world/kernel?
I've built/installed world/kernel (12-CURRENT) tracking
HEAD. Which is now at r314700. But was hoping I could
test a copy of r316100 by building everything in an
r314700 jail.

Thanks for any thoughts you'd care to share on this!
