Iam certain epoxy would work, and work well. Just dont try using a thick/gummy or real tacky exoxy mix. Use a real thin, almost finishing resin like epoxy, so it will soak in. Keep the 'hinge' area free from getting soaked up, and should work great.

Ilike the hole punch tip too. Toothpicks to anchor through them would be still efective as well, like the plastic dubro style.
