Can I add a second XG1v4 to connect to an additional TV?

I am here to request a second XG1v4 to be connected to a new TV.

I currently have two TVs... my main TV is connected to an XG1v4 box and a small kitchen TV is connected to an Xi3 companion box. Everything is working just fine with those. I am considering adding a third TV which will be 4K capable. I know I can get an Xi6 wireless box to handle the 4K programming that would work with an Xfinity XB6 Gateway. But I am using my own router and access points (with the Gateway in Bridge Mode), so that won't work with my setup. I want to use a coax connection for the third TV. I would like to use a 2nd XG1v4 to accomplish receiving 4K programming on this additional TV. The charge for that a couple of years ago would have been about $20 per month. I see that billing has changed on my account and my current XG1v4 and Xi3 both are now $7.50 each per month. If the second XG1v4 will be billed at $7.50 per month, I would like to have one shipped to me.
