space-time,
Your idea of adding a splitter before the cable modem will work. I have a similar setup. It will be able to transmit the network back through your coax wiring upstairs.
Here is setup from Instructables.com and it also has a similar situation.

One thing I don't see mentioned but you may be aware of already is that it is recommended to add a MoCA POE filter before the very first splitter. It prevents your network traffic from leaving your home.
