That is exactly what the "conntracking and NAT helpers" are doing for
protocols like FTP, where they permit a data connection when they see
a PORT command within the control connection.
You have to program this yourself, as an in-kernel module. You can take
existing helpers for reference. If you want to go that way, and you have
specific questions, best subscribe to the netfilter-devel mailing list.
