Aside from the two with Isam, and whatever Fain is up to, my hunch is that we won't see the Red Veils much except in the Blight (either as Lan advances, or toward the end battles).
I think we're going to see them quite a bit. They serve as an excellent wake up call to the Aiel that their ways are not always best, and seeing the opposite of your ways can often crystallize realization of what is wrong with them.
Added to which, you have a secret stash of lethal male and female channelers. Exactly why won't they be used?
