I have thought about shear bolts too. Notches on the aluminium or whatever material since we put more than one on the table, may also help. But there is a problem in this particular situation. The bike is going up and down,
Jumping around and occasionally having small crashes. If you have such a design you have to make sure that it will not break during riding... This may be very dangerous for the rider. That is the advantage of hdpe in certain places. It gives some room and comes back. There are too many variables too make a part that will self destruct safely in a crash. I think this could have been implemented by the teams but there is a reason that it has not been done.
