there is no simulator support that I know of.

It is not necessary to implement the tunnel with TCP as all protocols that use 
the tunnel already have a mechanism to detect packet lost. If you issue a HTTP 
query over a tunnel it will look like this:
HTTP -> TCP -> UDP Tunnel -> Internet

Your setup would look like this:
HTTP -> TCP -> TCP Tunnel -> Internet

Next to the overhead which comes with TCP you will face a double congestion 
window (see TCP congestion avoidance). In a lossy environment TCP over TCP 
connection will run at the lowest speed possible without a chance to recover.

Its not a problem - just somebody needs to do it.  :-)
