Sounds like a plan. you could turn a dummy slightly larger diameter than the bushes and fit that between each bracket to slightly remodel the brackets whilst keeping them square.

A 1U Network switch is 44.45mm heigh. :D

One thing to lookout for is the length of the bush tubes,if they are not all the same exact length you wil have a mismatch in measurements as I have found out my self and it all adds up to making suspension angles etc all to cock.
