There is a thread on the Resources board for this, you know.
In it, DeadManWalking statted up the Senior Council. He ranked McCoy quite highly.
He didn't write up LaFortier or Christos, but he did say that he'd probably put Christos at about 28-29 refresh. Presumably that'd be mostly Refinement with a social stunt or two.
I'd be willing to take a crack at him, using the "Deep One" power level and leaving a lot of spare refresh.
If you'd rather do it yourself, I can point you to a generic Senior Council member writeup that might serve as inspiration. It's on reply #42 of the Generic NPC thread.
PS: Ignore the OW Senior Council. They are ludicrously underpowered.
