Need advice on tub vent being outside the wall

[usnick1982]

Hello,
This is my second bath that i am remodeling. It had a triangular tiled in bath tub that i would like to replace with a freestanding tub. My problem is the vent pipe making a corner out of the wall (red arrow). Location of drain for tub is pretty much were it should be. Any options on hiding this vent bend in the wall? I was thinking about moving the whole drain to a joist space under the wall but that is complicated. Also 2 sinks drain into that as well.
Would it be okay to angle this wye towards the wall making it a flat vent? There is no toilet just a tub on that end
Thank you!

Does the p-trap stay in the same location or it move closer to the wall? The lavs will afford some wet venting if the tub drain is 2".
If you move the vent into the wall, you should add a cleanout for the future use of keeping that clear.

Thank you for your help! I dont know if i should move the ptrap but tub drain should be were the p trap is currently. Drain is 1 1/2. I can put a clean out if necessary. So if I rotate this wye towards the wall through the joist and put clean out would that work? I can not think of anything else.
Thank you again

And increase the tub drain to 2" so that there is room above the flow for venting.
With 1.5" you normally only go 42" to the vent.

Terry, thank you!
I thought i post what i ended up doing. There ended up to be actually a bit of slope to the vent so its not exactly horizontal

I don't want to pretend that I actually know what I'm doing with plumbing vents, but doesn't the vent connection to a horizontal pipe need to be rotated so the vent connection is in the upper half of the 2" drain (above the water flow)?

I am not an expert but seems like it was only option to hide it in the wall. I have added a cleanout to help with horizontal obstruction if it will occur.
