In practice, it may not be possible. No one has ever been severed twice before (I could be wrong, though). The first time someone is severed, it's usually pretty emotionally disturbing. The second time could be worse, since they lost the ability, got it back, then lost it again, which could have even greater reprocussions on the person who was severed.
I'm not strange. I'm normal. Everyone else is strange.
Oosta!
Never underestimate the power of the nerd!
Just for fun... Siuan's ability in the power...

That probably depends on if you think of severing as happening always at a single point.

In theory, it seems possible.

I think so. Esp. with Eldrene, Lews Therin and what we learned from Elayne's "unravelling" incident

Robert Jordan once said it may be used as a plot point.

I'd like to see them re-healed. It would be a good way to prove to the AS that men are equal
