I personally think yes, while staying at RBR means keeping an Adrian Newey masterpiece strapped to his backside, I think he really needs to get away from Helmet Marko and the Wunderkind's toxic environment.
Mark would be great for Ferrari for a number of reasons:
A/ He always give's his maximum no matter what happens and really knows how to fight back from adversity (had plenty of practice at it) vs Massa who just seems to give up most of the time.
B/ Webber is regarded as a very good development driver and paired up with Fernando, who is superb in this area, they could help bring Ferrari back to the front.
C/ Webber is a team player and wont do a Kimi on them.

D/ Ferrari would be an awesome place for Mark to finish up his career.

E/ It would pi$$ of boywonder as Mark would get to drive for Ferrari before him.
