Actually, it has already been done:

http://home.earthlink.net/~jknapka/vncpatch.html

At the beginning of a TCP stream, RFB clients wait for the server to
send a version string whereas HTTP servers wait for a client to send a
query string.  With the above patch, the VNC server waits for a HTTP
query from the client for a short time.  If it times out (2 seconds,
IIRC) then the server sends the RFB version and so forth.  It adds a
small delay to the very beginning of the RFB session, but it could be
pretty handy.  Tarantella does a similar thing for their firewall
traversal feature.
