It's doubtful, they haven't added hardly any to the satellite, so it isn't a priority to them. You could see an exception or two happen, for example Youtube TV has Comet which is an OTA subchannel in some markets. I think Dish carries one or two nationally as well. Really just comes down to the agreements they work out, but when it comes to the subchannels they sure haven't shown a want to carry them.
One issue is that the local stations want you t watch THEIR feed not a national one because of the advertising. If DTV and DISH are not willing to pay them then the stations would refer you do not get the national feed.
