karma, I'm going to give you some "cover" in regards to the IC
First of all, I think most ICs would prefer not to do MC as well or they shouldn't. Why? Basically, it's a conflict of interest.
In IC, the patient is the individual. In MC, the "patient" is the marriage in theory. You just can't switch modes like that. A reputable therapist shouldn't ask the either.
I would say something like this to your W. I worry that talking about us together would take away his ability to be a great IC to you. It seems that she has done well under this IC and to add you into the mix might not be a smart move. I would have no problem meeting (or in your case Skyping) with the guy though.
