Not really. They were pretty close, and I think overall Upton was better. Morse's BA and SLG was a touch higher, Upton's OBP was better. Upton crushed Morse in WAR because of the massive defensive disparity. Upton is a plus RF, Morse was an average-at-best 1b. Good enough for a two-win difference.
I said offensively. Morse had a marginally higher OPS/OPS+
And really, to quote MDS, "who gives a rat's ass." Morse is 30. Upton is 24. Who do you think will be better for the next 5-7 years?
Well, I care. Not because I wouldn't swap Morse for Upton (duh), but because I want to gauge how much I'd be willing to pay for him on top of Morse. His added offense this year could be less than keeping Morse. I would probably do JimBo's trade (and I think RZO would do it in a second), I probably wouldn't do the one you listed above (adding Desmond).
Morse doesn't make a lot of sense as a centerpiece, though.
