On your very own site you have photos and a LPH interview with “RF Burns” CC setup which IIRC uses a Radio Systems TR-6000 TX and is in operation even as we speak. So, what’s wrong with what he’s doing?
Don’t forget there are necessary peripherals (e.g., the coupler) for the LPB CC TX, even if you can find a working one for the price. Plus you need to have a maintenance schedule for keeping everything properly tuned and attenuated as necessary. It’s a cool way to do Part 15 broadcasting, but it’s definitely work.
Neutral injection does indeed bypass most transformer issues. I have no idea what the local power company would say about injecting a signal onto their system, or even if they would care. I know for a fact no one has a CC signal in my small town, or anywhere in the county … 4 ferry-served islands and many more that get power from OPALCO, which BTW, is a co-op. If you pay a power bill to them, you are automatically a voting member. It also has great management, we pay one of the lowest rates in the state.
