I'm going in opposite direction, gonna use aluminium bolts to hold rearsets on. At 1/3rd strength of steel, they might be just strong enough to hold everything together, yet snap easily during crash before any damage to frame is done. Maybe i'll do some destructive testing and if they don't snap easily enough, I'll hollow out the bolts slightly.

Run some quick numbers for a "realistic" shear and/or bending case that feasibly makes intuitive sense... you may be able to stick your aluminum bolts on the lathe and drill the centers to optimize their yield strength to what you need so it's strong enough for full rider weight plus some safety factor, but easy enough to break that you save the frame.
