As far as I can tell, access is provided to any OW lounge appropriate to the COS, based on either COS or ow elite status, with the following exceptions: a full lounge, or some specific exception such as what's going on with BA and CX at LHR. But other than that, a F pax can access any F or J ow lounge day of departure.
I'm certainly counting on this being the case, as I'll later be traveling HKG-NRT in JL F, and want to use The Wing.
As you said, never say never. It depends on the combination of the operating airline, and the airline operating the specific lounge. It is quite possible that you can get in the Wing.
As for the JL lounge in SFO, there is really no reason to spend time in it even if it is open and accessible as long as the passenger can get in the BA lounge.
