Well, that's a question you'd have to answer when/before registering
such an IDP within *your* local federation, before it ever makes it to
eduGAIN, no?
(Only stuff from local federations ever makes it to the eduGAIN MDS.)

So by definition this is not question of "eduGAIN supporting" this or
not.

eduGAIN -- as well as many academic large-scale multi-party
federations (outside HPC/Grid) -- is currently based on the exchange
of SAML 2.0 Metadata.
So if whatver you need can be expressed in SAML 2.0 Metadata -- and
the products expected to use that information can consume it from
there -- you're done: You put it into SAML 2.0 Metadata.

If OTOH the information needed to communicate between WS-Fed systems
*cannot* be expressed by SAML 2.0 Metadata you'd have to tell us what
that alternative means of communication is, exactly, and then we can
discuss whether to make "eduGAIN support" it.[1]
