Great idea by the OP, much easier than the big plate approach. One note for folks that plan to follow this route: steel + aluminum = galvanic couple... the aluminum is most likely going to corrode at the contact point with the steel clamp. A piece of thick lexan substituted for the aluminum would likely provide the same mounting strength but no corrosion risk.
