I’d honestly rather Red Hood keep his own solo title. The other Bats have had decades of their own solos already and to be honest Jason’s not been well treated outside of his own solo by most writers. He’s either used as comic relief, as the dumb muscle or he’s treated like crap.
Now if we’re talking about some sort of Bat Family anthology title that features stories or team ups where individual characters like Red Hood get an actual chance to shine. One that actually advances a character’s story and attempts to build on a character’s past established continuity because the writers involved take the time to actually research the characters involved that’s a different thing altogether.
