The happy ending for major characters (and Gawyn dying negates this for Egwene) precludes it, but Gawyn using one to help save the Light - and most importantly not being able to be Healed by Nyn. or anyone else before dying - would almost make up for his books worth of annoyance. Only if he dies and Egwene suffers the warder death backlash though. Otherwise hopefully just a trophy.
