That's a good idea. You might have to bend the lower stays to clear the canti studs.
I did this on a Sam with MR attached on the brake hole diving board bracket and the mid stay eyelets.
It had interference at the brake pivots. I bent the stays a bit like this:
It worked out okay. I had to futz with the stradle wire length to clear the bracket but it was do-able. You wouldn't have this problem with top of the crown eyes on the Bomba most likely. I imagine if you attach all the way down to the drop out eyelets you'd miss the pivots. IDK , looks like you would though.
Why do you want to attach them at the dropouts when you could clamp them in the middle of the fork anywhere you wish ? That way they'd be out of the way on a bus rack. The rack won't be any stronger attached to the dropouts as opposed to mid fork.
