getting around port blocking

I'm wondering if it would be possible to encapsulate one type of traffic into the port of another program. Specifically, would it be possible / safe to send other data on port 80 in order to get through a firewall? What about UDP? Any thoughts would be appreciated.

If we want to transfer an Ipv6 packets through old routers. we encapsulate all the packets in Ipv4 tunnel and then we send this Ipv6 stream to cross the classic Ipv4 path while at the end we get an Ipv6 address.
Plying with a port numbers is lot different and impossible.

So it would not be possible to run a game server on port 80 so as to get through a firewall? Might it be possible to build one's own protocol to support both http and a udp gaming protocol so that you could run a web server on port 80 and a game server on the same port, and the server could figure out by other means which data goes to what program, most likely with a custom intermediate fire-wall-ish program?
