I hope I understood it right: In the ContextFunction (within the MFA Flow) I try following:
scratchCtx=input.createSubcontext("org.opensaml.messaging.context.ScratchContext");
Which leads to a TypeError, this is not a function. Input is existing and of type PRC. 
Probably because createSubcontext is a protected and not a public function? Is there any other way to attach a ScratchContext to the PRC?

About the other concept, to set a flow-scoped variable:
within MFA:
flowscope=input.getSubcontext("net.shibboleth.idp.profile.context.SpringRequestContext").getRequestContext().getFlowScope();
I can put a variable there, though the SpringRequestContext is not beyond PRC after the transition from MFA to SAML flow.
Or did you have a different location in mind for a variable to pass on from mfa to saml-flow/discovery function


Thank you!
