Should be no problem. I've done it a few times. Just sand off the finish, get good matching surfaces, you only need about 1/4 inch to stiffen your tips, don't overdue it or the extra weight on the tips will slow the bow more than being whippy ended does. Taper the add on before gluing, its harder to do afterwards. You can even use superglue for this glue up. I use gorilla glue superglue for tips and add on's haven't had one fail yet, but it needs a couple hours to fully set up.
