Joey Porter at Inside Linebacker?

If it's true we are gunning for Calvin Pace, I would imagine the plan is to either move Pace or Porter inside.  Given Pace's athleticism and production at DE/OLB in the Card's hybrid, I have to think they want him outside.  But maybe they are thinking of moving Porter inside.  He's certainly big enough and has the coverage skills.  Could he hold up against run after run up the middle is the question I guess.  Has anybody seen any speculation online from the Dolphins or anyone else on moving Porter inside?  Anything negative or positive?  Just curious.
