Can you expand on the light green bumper mounts? Is it a piece of C channel with an additional L bracket on top? Was this primarily for additional support vertically, as the bumpers are really only supported along the bottom edge by the frame?
We always try to keep our frame in the center of the bumpers, which has allowed us to use some C-channel sized to fit snugly over the kit frame, without any additional supports. Of course, we've always used nuts and bolts, so it's been a pain to take the bumpers on and off. Fortunately, we've used reversible bumpers the past two years, so that hasn't been a problem!
Bonus points: attach the pins to the bumpers through a small cord (many of those quick release pins have holes pre-drilled specifically for this!) so you don't lose a pin!

I'll attach a closeup for clarity.
The 2 clip pieces are made from the kit channel (the lower one is just cut to length) and the 2 are welded together. This allows for the bumper backing to be fixtured at the desired height and attached to the bumper clip (in place) via wood screws. Depending on bumper height, the clips could also be mounted "upside down" as shown in second illustration. Connecting 2 perpendicular sections of bumper handles the bending moment so that the clips do not have to be centered on the bumper backing (helps save weight by not having structure dedicated to bumper support). And, yes we are considering tethers (non-conductive for sure!).
