Good Idea, John.
And look on the bright side of things, if you ever did decide that a bayonette would be a good thing to have, there is always plug bayonettes.
I would still think about getting some sighting shots off, though. If you do have to add some height to the front sight, you might weld a bead on top then clean the whole thing up with a couple of passes through the mill.
By the way, I cannot recall anyone ever telling me I was too PC/HC myself. Like you, far from it.
