I was just thinking of this the other day. It would make up for some interestng narratives, if the writers choose to take this direction.

As for the discussion on demon age, I think it is still a major (NOT the ONLY) factor in determining power/strength. Crowley is still actually weak and vulnerable to holy water. If he did actually receive a power boost, it may be because he now had access to the souls of hell, whereas previously, he only held souls reaped from crossroad contracts.
