Makes a huge difference if they trade him pre-season or at the deadline. You would get a lot better return now than at the deadline. Hence if you are going to trade him anyway, do the pre-season!!
If they do it with the Mets now, maybe something like Baty, Gilbert and Acuna.
I would prefer Vientos in the deal over Baty, not sure if the Mets would do that unless it was some trade and sign deal.
