Sounds like you are getting some good results.
I’ve got 3 bananas and some ripening tomatoes in a paper grocery bag trying to ripen one green tomatoe that fell off early.
Gonna give it a week and see if it starts to turn - nothing yet after about 48 hours yesterday. I’ll check again.
The ethylene gas coming off the bananas (and maybe the tomatoes?) is supposed to help tomatoes ripen, even green.
