Sorry to be realistic but if you want any chance of an op-up as 2 blues, take the POUG to WT+. They are probably offering you a POUG because WT is oversold but they are not specifically offering it to you because they are planning to upgrade you if you don't take it. As WT+ is the smallest cabin it is the one from which you are most likely to be upgraded.
On a JFK flight there will be lots of status passengers (from bronze to GGL and all the OW equivalents), even in WT. They will all be ahead of you in the queue for an op-up. Additionally, although couples op-ups do happen it is much easier for them to upgrade single travellers (potentially less shifting around of seats in the cabin).
