What happens if you triangulate crumple zones?

(OP)
In the first image the read arrows pinpoint the aluminum crumple zones.

What would happen if you add some x-braces?
Depicted in red in the second image.

Also, do the holes drilled in the aluminum beams help deformation upon impact?

RE: What happens if you triangulate crumple zones?
The holes are almost certainly to control where the beams start deforming when subjected to crash forces (acting as a column). Crash structures very commonly have designed-in holes, folds, bends, etc., in order to control where and how the structure deforms.
And now for the big question ... Why are you interested in stiffening in the manner shown? All it's going to do during normal driving is to add weight to both ends of the vehicle (bad) and stiffen the bumper from moving sideways (irrelevant for any purpose that I can see). The places where stiffness matters are all between the wheels. Anything hanging out over the ends beyond where the suspension attaches to the chassis, doesn't matter so much ... except for crash structures.
