Shower / Toilet Vent

Hello all,
In the process of installing a new shower pan and toilet and I figured I'd clean up the previous owners drain plumbing mess.

Would the attached drawing be a proper location for a vent for both the shower and toilet, or does the vent need to be downstream of where the Toilet drain Wye enters the main line to the septic tank?

Shower / Toilet Vent

The vent is fine, it should be 2in. you can't run that trap that way, you should come into the side of the 3in. with a wye

Shower / Toilet Vent

Unfortunately, the vent is 1 1/2" all the way up through the second floor, and without tearing out a good amount of drywall the entire length can't be replaced.

What is wrong with the shower trap? All the connections will be made using a wye / 45 combo. with the connection made to the top of the main.
