the thing is that this is a straight up trade. If you give 5 players to get one you can use terms as "giving up too much", so I really dont understand that way of thinking? How can that be too much? If you gave both of those for McCoy it is probably too much. This is a straight up value comparison.
I would do this trade ASAP before fjax gets healthy. Even with fjax done for the year, I think I'd prefer McCoy over Spiller. With Vick out there is going to be a more normal running scheme in philly and I expect McCoy to get ALOT of touches per match going forward.
I would also prefer the stability of a Peyton Manning throwing to Thomas than Matt Ryan to Julio, but the biggest sell for me would be aquiring McCoy.
