You might try drilling for all your screws and hardware, and then soaking the lure in some kind of penetrating sealer, like Minwax Wood Hardener, before you seal with propionate. That way, the wood around the screws and hardware is sealed, too.
For small balsa cranks, I use runny Crazy glue in the screw eye holes, and as a sealer, too, to keep the weight down. It holds up fine, but I only fish for bass, which have very small teeth, and usually inhale the bait, instead of impaling it, like I've seen in pictures of Musky and Pike.
And I would install the screws before I top coat. It's a little bit of a pain to clean out the eyes, and extra step, but it is better than having the top coat fail.
