Enlarging the master bath shower since the furnace flue is no longer required adn I need to move the vent for the DWV about 2' to get the maximum area for the new shower. The vent is attached to the main drain for all fixtures except the kitchen sink which drains down the vent. NOTE: Th main drain and vent are 3" Sched 40. Can I (1) ell off the vertical wye from the horizontal drain run - run a 3" horizontal line for approx 18" and then ell back up vertical - reattach the kitchen drain or (2) do I need to have the entire vent move the required distance?
Any advice is appreciated. Pics follow

Your description makes sense to you, because you are looking at it, but I really have no idea how you are doing it.

If you use a long sweep 90 at the base of the stack, and the horizontal section of piping is being washed by a fixture, then yes you can do as you proposed.

You probably do not have enough height to make TWO 90 degree turns below the floor, and it would violate the "no horizontal vents below the overflow level of the fixtures" rule. It is indistinct, but is there some kind of joint at the floor level. Your photo seems to show one but cuts off before making it distinct.

I believe that's expanding foam insulation you are seeing at the subfloor.

Possibly. As I said the photo is too indistinct or in shadows to tell what it is.
