What about velcro closures instead? Applying snaps seems like a lot of work for something that might look wonky. You could sew the buttonholes closed, move the buttons & stitch them on top of the closed buttonholes, then apply velcro (hook & loop) dots underneath....

I think I would NOT cut off the buttons, but leave them. I would sew one part of the snap behind the button and put a small piece of fabric or interfacing behind the buttonhole and sew the buttonhole shut, then sew on the snap. This should not only make it easier for your husband, but not alter the look of the shirt when snapped.

Donna, the snaps I have are the kind like they put on western shirts, not the kind you sew on.

Ah, then I think your idea should work.
