Replying to Adjusting forward lean with binding risers plates

Alright here is my idea, I have Head raptors and I love the boot but I feel like it has a tad too much forward lean for park but I love how to boot skis on the rest of the mountain so I don't want to do a cuff modification. So I'm thinking I could make a few mm riser plate out of plastic to mount under the binding toes to effectively decrease the forward lean angle of my boots. Obviously I'm gonna need longer binding screws but I think I'm going to install QuiverKiller inserts in the ski anyways so it would be pretty easy to just get some longer machine screws. Anyone think this will work well or has anyone done this?
