I think Alcantara certainly should be in play. Theres a pretty slim chance that he ever plays for the Cubs, they need to solve that roster crunch, and he's dripping with tools on a rare physical stature, he should be quite coveted.
Wicks and Ferris probably aren't going to be enough to headline a deal like that. I do think that Ferris would be quite a secondary piece with his pedigree and easy LH velo at a young age.
These are exactly the guys that we should be packaging; guys with high ceilings that probably won't be of major consequence for a few years to our MLB roster. Not crazy about buying a reliever and I'll be less than surprised when he falls off a cliff upon donning the Cubs uniform. But it would fill a huge need and keep the near future intact. The Cubs have the depth to withstand a deal like that easily.
