Rather than devise such a new scheme, think about why SenderID, SPF,

Yet they are not implemented.
I suspect that the majority of email sent has three of those four
implemented. If not quite a majority it's _definitely_ a large fraction.
(Yes, I'm cheating. Nobody other than the very, very gullible
implements SenderID as such, but a valid SPF record is also a valid
SenderID record).
Proving who the sender is would be huge -- it would allow for
prosecution for illegal spamming; it would alert a user whose
computer is infected and used as a bot, and it will allow for
blacklisting (reputation loss).
So, before you create a new parallel mail system that costs money
and has cross payment systems, etc., why not get these standards
implement fully?
Methinks it's not technology alone that's the problem.
