If I were you I'd be very wary this doesn't come back and bite you, as Tony stated magnetic repulsion under heavy fault current can do some nasty things. Think about what happens when a steel cable snaps under load,then imagine that level of force as a whip being cracked,a bit of thin trunking is not going to hold it,that's why busbar chambers are thick steel and the busbars are clamped down tight.
