First of all, the inverters are PS series, not SW.
Second, I have created a solution: I can acquire a transformer that
will connect a primary across two of the 208 generator phases and
create 120/240 off of the secondary. This will imbalance the
generator but the genset is 37 kva so the inverter loads are
inconsequential.

That should work.
I seem to remember that the SW and PS, even when stacked with the cable
will sync up to the generator
or grid by whatever is presented at its grid or gen input. I think the
stacking cable only synched up the inverter phase to
be 180 degrees when inverting as well as coordinating the charging
functions.
Your transformer would certainly keep away the re-synching from 120
degrees to 180 degrees as Phil was talking about.
Otherwise, some kind of delay-relay might have been necessary until the
phases got right if 240V loads were on the
PS outputs.

Friends:
Is there any way to connect two SW series inverters to two
phases of a three phase generator? It seems to me that one
could connect three SW inverters with the right stacking cable
(or am I confusing Outback inverters with the hub jumper set
properly).
Any input is appreciated.
Thanks,
William
