Looks like the makings of a nice mod! I agree that the pins should be put through the wood. Simple epoxy or CA is not enough to hold that wood in place. If that knife is ever dropped those covers would probably fall off from the shock. I can understand, though, if you do not want to take the knife apart, that can be intimidating if you've never done it before.
However, that is part of the fun and learning process.
Please show pics of your finished knife!
