Yes, its possible and we do exactly that in conjunction with Exchange 2013.
We're using a call-ahead db which is configured in milter-ahead.cf:
cache-type=bdb
call-ahead-db=/usr/local/milter/milter-ahead/call-ahead-table.db

The source of the call-ahead db is a call-ahead table:

exchange2013.our.domain  [10.1.2.3,2525]

The delimiter between ip and port looks a little bit odd,
but for IPv6 compatibility, the comma is better than a colon.

make db from table:
makemap hash call-ahead-table.db < call-ahead-table

The entry for the domain in mailertable is as usual, so for the recipient
check,
port 2525 ist used, but the transport goes over port 25.


Cheers,
Sebastian
