That doesn't sound easy. One aspect is that invitation needs to be 
consistent with its form. I.e. if I send an invitation to register a 
user that invitation is bound to some form, say form1. Now after 
rewriting it to be an invitation to an enquiry, it would require a form 
which is 100% compatible with form1, but cut down to be enquiry. It is 
possible but would require to create automatically a read-only, system 
enquiry form for each registration form, with compatible contents.

Another concern is around detection of how the user is subscribed "in 
the meantime". In general this can happen in plenty of ways, and we 
would need a generic mechanism: new entity was added; let's check if it 
has a confirmed email (hmm, identity or also an attribute?) which is 
used in any registration invitation, and if yes rewrite those 
invitations to enquiries.

All in all that is doable, perhaps even generally useful, but it is 
rather a major development to cover quite of an edge case. Maybe we can 
think about something more lightweight to support this scenario?

Cheers,
Krzysztof
