So technically this is a viable solution ("we don't lose the ability to
leverage the SOAP processing model") right? If yes, I will write up some
scenario for using it (intermediary/management/proxy type of scenario)

Thanks,

I'm still unclear as to why you think it necessary. If an endpoint
publishes an EPR with ref props and/or params, one assumes that it is
doing so full in the knowledge as to what it intends to do with these as
SOAP headers.
The one thing that distinguishes them in the context of an EPR is that
ref props are used in determinging EPR equivalence (e.g. that the two
equivalent EPRs have the same metadata (WSDL, schema, policy, etc.) The
intent of defining EPR equivalence is specifically so that the sending
node can know which policies it can expect will be applied (or which to
apply).
