I don't think he will be able to use saisar just like that. He would have to link with a female channeler for that, most likely Pevara.
But maybe both of them will have greater control over the OP when linked, and thus be stronger.
I doubt it will be exactly like that. The double-bond will be important, yes, but not this way. I believe it will be more like a tool to communicate between people during the Last Battle. Like built-in walkie-talkies. That would be nice, personal radio's...
