I think no, posting styles won't look at the headers of messages you
compose. My understanding is the styles are only in effect for a) group
names, when you're composing a message to a specific group, and b)
messages you're replying to, in which case the styles match on the
headers of the original (received) message. I don't think you can do it
based on outgoing message headers. How would gnus know which of the
gnus-posting-style entries were meant to match on outgoing messages, and
which meant to match on replied messages?

I've thought off and on about a wrapper for mail composition, which
would first query you for a few headers, and then set up the message
accordingly. That would provide a place to run hooks like what you want,
but until someone writes that wrapper...
