I have done bolted neck conversions, but I generally consider it only on cheap guitars.
The wedge fingerboard is a good option, as long as you don't mind the neck getting thicker at the body. If you do, the neck can be reshaped, but that would require refinishing the neck.
The block can be slipped by taking the back loose in the upper bout. This is also known as the 'California neck set'. After the block is reglued in the new position, the back is trimmed and the binding reinstalled. At least some finish touchup is normal. The most difficult part is separating the back from the block without damaging it. This is a repair that will benefit from experience.
