James Spader as a guest?

I wonder if Shatner will try to interview James Spader on "Shatner's Raw Nerve." I've read that off the set on "Boston Legal," they weren't close. Spader supposedly said he "respected" Shatner as an actor. I imagine Shatner, being the competitive type, rubs some of his co-stars the wrong way (like a few of his "Star Trek" castmates). And Spader doesn't do a lot of interviews. Still, a sitdown between the two actors might be interesting.
