They might feel different about this. In 2023, Geezer was saying he is deaf in one ear and has tinnitus in the other. I can tell you from my own experience that hearing problems take a lot of the fun out of playing music.
On top of that, one reason why Geezer quit Deadland Ritual was because he didn't like going back to playing small places and living in tour buses and cheap hotels. He basically said it doesn't work for him after riding high with Black Sabbath.
Even if Geezer and Tony got a new band together, it would be small scale without Ozzy.
