Bolt, Moca & TiVo Bridge

My TiVo Bolt is nowhere near an Internet Ethernet connection. I have 3 TiVo minis in other rooms with coax connected to them. Everything is connected together via coax so a Moca network should work. I have an OTA antenna also connected with a POE so no issue there.

My question. Obviously I can't use the Bolt to create the Moca. Can I create the Moca with the TiVo bridge, run the coax to a splitter near one of the TiVo minis and inject the Moca there? Seems to me it shouldn't matter where the Moca is created within the coax network.

Thanks.
