Should I sell my five stars?

Frustrated1

How would it effect my scaling?

I have one of every 5*, but only one cover each (Logan has two and is maxed at 285. I haven't put ISO in the others).

I have all of the 3*s, but not all champed (most). Ive got most 4*'s but only XFWolverine and Invisible Woman maxed. Fury, GRider and a couple others are getting up there, but none over 200.

So will selling any/all 5*s help my scaling?
