How should I build this section of my wall?

I am getting ready to add an addition to my garage gym. Currently I have a tension board and want some lower angle terrain to compliment it. My main goal is to add easier terrain to do my ARC or LBC on, also it will really help my wife to have more easy terrain. I was wanting a 12' 20 degree wall and my max height it 10' 6". I am also trying to work around a beam that runs along the length of my garage. If I am just making a basic 20 degree wall I can have the top end either 5" or 1' from the beam depending on how large of a kick board I make. I am concerned about that beam getting in the way which is getting me interested in more creative option like having the 20 degree wall come down just on the other side of the beam, and then connecting it with a short 40 section to connect it to the wall. Here is the mockup of what I am thinking, sorry I cannot figure out how to get big photos on here...

I love this idea cause it seems like a cool way to get some extra terrain and with a sit start my wife could still start with her hands on the 20 degree wall. If I did do this I would likely notch out the 2x6 so that it could sit in flush against the beam which would drop the angle of the little 40 degree section to about 38 degree which is not much but something. Along with standard framing stuff I was planning on putting a 3/4" OSB brace on both sides of the joint to help stiffen it. I would also likely connect this to the wall behind it at the joint as well. Here are my questions?

is all this extra work worth it, or should I just build a standard 20 degree wall?

If you have used a wall like this will it end up having the easier terrain I am looking for or be more difficult than I imagine? I really want this part of the garage gym to be better suited to my wife.

Will 2 OSB braces and another joist connecting it to the wall be enough to keep this thing from falling apart?

Will notching out the 2x6 to fit right next to the beam weaken it significantly enough for failure?

Any other suggestions?

I would build a 20 degree wall either right in front of the beam or hung from it with sleepers across your floor joists at the top of the wall that the plywood ties into. This lets you keep the top 1’ of climbing wall in front of the beam at 20 degrees and buys you an extra 6” in floor space. Don’t do the 40 degree start, leave a doorway and keep all your storage behind the wall. The broken plane will cut your opportunities for endurance type sessions and litter the bottom of your wall with jugs. With small walls clean single planes are the best for training.

No need for a kicker on a 20 degree wall.

Cool, this is what I ended up deciding to do. I will be getting started on building this weekend and hope to be done after thanksgiving. Once its all in I will show it off on here.
