That's pretty cool... I did something somewhat similar a long while ago, except I had the configuration the other way, the bearing surface was on the neck and the "saddle was a separate piece on the guitar, and the bearing surfaces were slightly eccentric so that when the action was raised, the neck actually pulled toward the body and vice versa. I also pocketed the heel into the body to make it less "visible". I also used a heavy spring to keep tension on the lower bolt, so the neck wouldn't move if I changed strings. Unfortunately I knocked the guitar over and I took too much off the heel block and the whole thing exploded before I could touch it up! But cool ideas here..
The only thing with the finger joint is that it may look a little funny once you carve the heel area...
