I think there's potential there, but it's hard to ask people that can barely sustain their existence to spend time they could be using to earn money is a bit complicated, if there were some true promise of true economical compensation, maybe, but for that you need to expropriate some land which would never happen in the US because their military industry is too big, that generally happens like in countries with heavy levels of peasantry.

expropriate some land
This happened vaguely during blm with a police station. Mobilize the homeless and convince them they can stay in a police station, which would benefit somehow or something... not sure.
A handful of homeless/very poor come out during protests already about housing rights or to increase welfare. At least 1 homeless guy i met goes out to every antimask protest. A lot of them go out to church services on sunday, even the church services that are not in a shelter.
Or if a riot has like the promise of seizing a target again, that's something. But i wouldnt recommend a riot.
What about trying to promote some anti work shit on /r/homeless plus trying to create groups of like minded people who are in the same situation? It may be a better way to try to start something than in person.
Unfortunately, from what i've seen, if the venue being seized has a lot of cigarettes, that would also maybe convince some homeless
I would most certainly join the revolution if they promise me free cigarettes.
