(Marvel) Could Xavier prevent Banner from becoming Hulk?

If Xavier built a mental block into Banner, could he prevent Banner from triggering Hulk?

It could work temporarily, but The Hulk is not just a part of Banner, mentally.  I'd imagine  psychic blocks would work a little more effectively than meditation, but as soon as Bruce was put in danger (as he occasionally finds himself), The Hulk would overpower them.  The Hulk won't allow Banner to die, and if I've learned anything about The Hulk is, he gets his way.
