It would have to be "de-tunneled" on the inside to do something useful. Either
the network is already compromised, or it exploits something on that specific
service.

Leverage existing code.

Windows 2003 already knows how to tunnel RPC over https.

And quite frankly, any sentence that has "Windows" and "RPC" in it is all too
close to "already compromised"......
