You may be treating a symptom rather than a cause here?
If you are not controlling that pronation with an adequately posted footbed, making more room for your navicular may just make room for more pronation and once again have your navicular pressing against the shell?
I would reassess my footbed function if I were you, before punching or grinding. Yes, indeed I should... but a posted footbed would add too much volume and compress my instep.
FWIW, if I'm lying on the couch with my foot in the air, completely unweighted, I can observe curvatures in the medial surface of my feet, and there are two curvatures that need attention via punching of the shell. The first is the 1st met head, which has been done. The second is this navicular region. Maybe it does protrude, I guess I'm not a foot expert so can't make a call if it does or not.
I'm just thinking of ways to alleviate instep pressure. I need every cubic centimeter I can get.
However, I will add that I will keep your last point in mind whenever I get myself a pair of boots with a taller instep.
When doing 1-legged upside-down bosu ball squats at the gym, I find my foot is stronger (or at least prefers) the SUPINATED position. Does that mean I'm a supinator, or the opposite?
