It is not one of the corner configurations shown in the game manual, and as Eric noted, bumpers are one of the few cases where something is not allowed unless it is explicitly allowed. As such, I would suggest a Q&A if you are considering this. The half-thick pool noodle on the rabbet side will not have the usual compression characteristics of pool noodle, especially if cored. Corners are where you want the bumpers to work best.

Note that the wooden part of the butt end may not extend more than 1" beyond the frame perimeter ber R21 b. When/if you submit your question to Q&A, I would also include in the diagram where the wood is located.

I would not consider rabbeting the wooden part of the joint to be legal, per R21a, as that part of the wood would only be (e.g.) 3/8" thick.
