Only remaining question then is whether there is still a penalty of shortened lifespan even after the Oaths are removed. It's possible that removing the Oaths only partially increases lifespan again.

I think it would be very cool to see Egwene and Mesaana fight in T'A'R, both are masters of that world so it will beat Rand's fumbling around with Rahvin.

That said, I still kinda hope that Mesaana is killed by one of the Bloodknives, thinking that she is just a regular AS. Would certainly fit with the deaths of the other Forsaken.
