Feel free, but my advice is that your requirements are misguided.
Postfix can be a non-queueing proxy in front of another MTA by the
way, if you make sure that the ESMTP feature-set of the back-end
MTA are is the same as that advertised by Postfix.
I've done this to add TLS support for non-TLS capabable MTAs without
introducing an intermediate queue.

Still not a good idea in general.
