Are you saying the exhaust would travel up to a passage on the top of the back and then need to be drawn down thru the false wall to a cutout in the middle of the outer back wall? Like traveling thru an "S".... Is that correct?
Make no mistake, there ain't no powder in this Puff ! And... I'm not really a crazy person but I play one in real life
The exhaust would be in the middle of the back wall, just like on a Backwoods. However, instead of having false walls on the side for the heat to enter, the heat would travel up a false back wall (on either side of the exhaust)
And on the eighth day God created barbecue …. because he DOES love us and he wants us to be happy.
Current smokers: Egor (trailered RF) and Easybake (tabletop pellet drive)
The simplest way I believe is to not try to create a duct/s for the heat but rather an opening only on the Baffle Plate on each side. Then I would put 2 openings for the exhaust one in the middle at the back and the other above it at the top. I say that because it would allow you to be able to adjust how long that smoke stays in the CC. You don't want it to grow stale, but rather keep moving.

Current Smokers: Backyard RF Offset and Hybrid RF Offset trailer rig with Cowboy cooker and fish fryer, always room for more........
I believe the BBQ vault/safe by Pittmaker has a false wall in the back that brings in smoke/heat from the fire box and they add two C channels along the sides to vent up to the top exhaust. Take a quick glance at their models.
I think you're talking about dividing the back false wall in to thirds and having (2/3) bringing in heat and (1/3) exhausting out to the exhaust stack.
Yep, that is exactly what I am talking about. Feedback/comments on how it might work?

I could see where this idea would simplify the build. But I don't know how to size the intake/exhaust stacks for the vertical style smokers. In comparison, the Pittmaker used the whole back false wall for an intake, and the Backwoods uses majority of both false sidewalls as an intake(to bring in the heat/smoke into the cooking chamber).
In the design you describe, only 2/3rd's of the back false wall would be the intake which isn't as much. You may could make the false wall deeper to compensate for that, but I'm not sure what other complications that would cause.
I think this style would work. You might want to try to Deflect the smoke to the front of the smoker so that you do not have the smoke only in the back of the smoker. This style gets most of the heat into the cooking chamber through radiant heat through the plate or water pan between the fire box and the cc.
I never saw much need to a RF for a vertical cooker. With a horizontal, you need to divert the heat and smoke to even out the temps . With a vertical, a simple baffle plate, water pan or deflectors are all you need.
If it's tourist season, how come I can't shoot 'em?
I'm glad you posted this question as I'm currently trying to design one for me and thought the same thing. I also thought about designing mine to be both a pellet burner and like a backwoods/pitmaker. Maybe i'm making it too complecated.

No reason you couldn't do it all in the back wall.
I just wanted didn't want to lose that space on the back wall, for more depth, so I went outside with my exhaust.
Up thru the wall would be slicker.
