It’s not that hard or expensive. CATV analog modulators were common in the past. I had 8 in-home TV channels until our cable company went digital.

It's definitely possible to transmit multiple TV channels at once, and I have experimented with that in the past. Since TV channels are 6 to 8 MHz wide (depending on what part of the world you're in) there are practical limits to how many channels can be transmitted at once. Consumer-grade SDR boards are limited to about 56 MHz total bandwidth, which would be enough for 7-9 channels.
Something that people ask occasionally is how to use their vintage TV's tuner to receive digital TV. But they don't want to tune it to channel 3 and then change the channel with a digital TV box; they actually want to change the channel with the old tuner. The current advice seems to be to spend $hundreds to get an analog CATV head-end, and a separate digital tuner for each channel, but I've never heard of anyone actually following through and doing that.
