Could you run the shower trap arm diagonally over to the area where the Homer bucket is?
Or use a combo instead of the vent tee, and run the lavatory thru that rather than where it is going now? That turns it into a wet vent, which has easier rules.
Yes.I’m not sure what you mean. Are you saying I would just do away with the entire dry vent?
You would use the combo or a wye to introduce the lavatory drainage (including wet vent) between the tub and the shower.Where are you saying to put the Combo? I’m all for simplifying this if possible

You have a maximum trap arm length, with a 2 inch trap and 2 inch pipe, of 8 ft. So that can be a factor too. Where does 8 ft for the tub trap arm come to?
Yes, that is one way. Maintain the 1/4 inch per slope from the lavatory trap adapter until at least the vent connection.I tried to use my iPhone to edit the photo for what I think you’re saying. Is this what you’re saying?

Vent connection to the trap arm with IPC can be a santee on its back.
Logic says two dry vents in this wet vent scheme should be fine, but there may be other interpretations. I am not a plumber. If you put a wye in the 45-degree pipe and ran the lavatory drain horizontally to there to get vented, I think everybody would like that. But your method seems like it should be better. It's just not something I am sure of.
Check the drawing on page 12: https://www.iccsafe.org/wp-content/uploads/20-18927_GR_2021_Plumbing_Venting_Brochure.pdfSorry I know this is asking a lot, but is there any way you could sketch that for me? I’m having a hard time figuring out exactly what you mean
This is awkward, but...
