I'm going to go out on a limb and say that while this is an ingenious idea, it probably won't be approved. Quoting <R12>, "Therefore, each ROBOT must be able to display red BUMPERS and blue BUMPERS This may be done via either of two acceptable methods:" and then it goes on to list the methods.

What they don't say is if any other method is acceptable. That's what I'd ask. If I had Q&A access, I would say something like: "We have found another method to change bumper color. We would like to know if we are allowed to use this method. [describe method] If this is not legal, we would also like to know which rule it specifically violates."

Like I say, I'm not sure this method would go through, but I'd love it if it did. I'd also use the grommet attachment suggested.
