Replying to DIY Binding Plates

Ive got some 03 atomic stomps that use the heavy heavy atomic 412 bindings. The one thing i hate about the skis are that you can only mount the atomic binding to the binding plate because the ski isnt flat at the waist. Do you think it will work, if I take the new bindings and get a perfect match of the bottom of the binding made out of steel to make a riser ( same idea as skateboard risers) and just drill threw the steel and secure the bindings to the skis using longer screws and if so will they hold?
