You'll be able to decide how you want to prioritize the fields - I've
implemented it as a DNS server, so which domain you decide to send to
the DNS server is entirely up to you.

That sounds like it might be possible to game things by playing with
the order.
I'm not sure what sorts of validations are applied to the Sender:
header. (I don't remember if DMARC checks the Sender: header or not.)
How would your filter respond if the MAIL FROM: and the From: header
were set to something that didn't have a website, yet had a Sender:
header with <something>@gmail.com listed before the Reply-To: and
From: headers?
