There's lots of unused space in JFK T4 just past the new security checkpoint, in the upper level area which used to be landside and where several lounges are / have been, so that's certainly possible. If Amex is trying to reduce payments to airline lounge partners perhaps T8 is also a target, though I'm not sure if there's any space in T8.
I wonder if we will see Amex start offering these lounges as contract lounges to carriers flying into these airports. I could see carriers like QR at T8 and EY at T4 wanting to offer something more like the Centurion Lounge to their premium passengers rather than the Admirals' Club or a generic contract lounge respectively. Likewise with EK and possibly others at DFW, and perhaps VS at LAS.
Good to know that there is space in T4. I haven't been through since the expansion opened/security moved, but that seems like a logical place then for one of these (and might be enough to convince me to fly out of JFK rather than LGA, given the right price/times).
To me, T4 makes more sense than T8, since it hits more airlines and hits a largely international audience (rather than a mix). But they do do already have 2 lounges in T4 (Oasis via PP and Delta SkyClub, which I'm sure isn't going anywhere).
