If you could get ALR on 2 years plus an option, then that might be ideal. The rest of the decisions line up.
I don't disagree with those who think Morse is risky for a long term contract. Any decline in the muzzle velocity when he hits and he becomes a bad outfielder whose OBP declines from .340 to .320 with a bit of residual pop. If he has a year like this year (he's going to finish with very good numbers, HRs and RBIs that most players will not put up in a full season), then you maybe add a year. I compared his contract to Ortiz. I don't recall him ever having a 3 year contract despite being near-MVp in his prime. That is Morse's situation. Not saying he is Ortiz, but just that with the contract leverage and the questionable projections (Ortiz - body and decline in the late 00s, Morse the plate discipline and lack of skills for D in the NL), he will not get a long term contract.
As for the White Whale, with ALR, there is no need to go outside the organization right away. Ellsbury might be ideal, but you wait for his free agency because, as a Boras client, you are going to pay either way. Might as well not strip the team while you are doing it. If Ells hits the market and Goodwin looks like he's not the real deal, then you consider signing him and maybe dealing Goodwin while you can still sell the sizzle. More likely, you laugh all the way to the bank with the money you are saving and wait for Goodwin.
