I have not yet seen a proposal that fully handles this case. The current
 PAOS specification [1] uses non-WS-Addressing SOAP header blocks. I
will note, however, that Dave Orchard did address PAOS in [2], providing
for the presence of a paos:reverseBinding element in a WSDL document,
and noting that the paos:reverseBinding would still need to be written.

It seems to me that we would merely need to complete the definition of
the paos:reverseBinding as mentioned in [2].
