Your main problem will be system routing.

even though you can bind your socket to the relevant public IP for whichever modem you wish to use, when you try to connect on that socket, the OS will route the outbound SYN packet (setting up the connection) out the interface with the lowest metric.  This in general will be the last modem connected.

You could try something like WinGate, which can override system routing and force traffic out specific modems.  e.g. set up 8 WWW proxies in WinGate (on different port numbers), set each to connect out through a specific modem, then from your client code, direct your connections to the proxy relating to the modem you want to use.
