Did you plan some sort of end caps (possibly semicircular) to serve as frame perimeter behind the bumpers on the short end?

Lots of small details would need to be tweaked to make sure all of the rules are met. This is one of those ones I'd put on the list of "things to fix before bagging". It's usually a very long list.

There would need to be some added support structure to satisfy the bumper rules (at least, if the rules stay the same next year). It wouldn't actually make the frame any stronger; the plywood portion of the bumper could easily handle all of the load from an impact.... but rules are rules. Bumpers seem to be one of those things where the letter of the rule is more important than the intent.
