JTG, as a board member friend please read Powerless, please read Astonishing X-men.
Also, think of Wolverine.
If he lost his power of healing, etc, he would still make one hell of a character.
He is trained in most forms of arm to arm combat. He is a trained Samurai. He would still have an Admantium covering over his skeleton. He would find it difficult to release those claws but as they were part of him prior to the esperiment he could still use them (although he would not re-heal his hands once they popped).
But most of all, Weapon X are not wholey responsible for wiping his memory. His healing power is constantly wiping the trauma from his mind.
And so, if he was injected with the "Cure", then he should be able to, with Xavier's help, truly find out what happened at Weapon X and then also, more importantly, remember who is and his childhood.
I think out of all the characters Mr Howlett would be the most interesting to see lose or give up or have taken away from him, his powers.
p.s. I don't remember Elektra or Punisher having powers. It is their need to fill an unfillable hole created through loss that has driven them.
