I am told that TDMF provides access to devices via SCS0 only.

I have no experience with FDRPAS or its IBM counterparts (like TDMF, if
I recall correctly). However, unless they are able to talk to devices
in subchannel sets other than SCS0, none would solve Skip's problem.
I'm afraid I don't know whether any of them talk to devices outside
SCS0, and nobody I know who might be able to answer that question seems
to be around this afternoon.
I am not really a Storage guy, so I don't know whether it fits the bill
from an ease-of-use (or cost) point of view, but as PPRC secondaries and
FlashCopy targets *can* be defined in SCSs other than zero, one could
for example potentially establish (for example) the needed PPRC pairs,
let PPRC do the copies, and then take the primaries offline. Whether
this would work, and whether it could even be done with HyperSwap so
there was no required outage, is another question I'd need those same
people for...the ones that aren't around today, I mean.
