Is there a way to add lesser cant than the standard +/- 7 degree Burton "wedge and metal puck" to a Burton/Ibex binding (without using the Unicant)?

I'm thinking of using the 7 degree in the back (wedge+puck) and something like 3 degrees in the front, but there's no way I'm putting a Unicant (Varicant?) up front.

There's a reference to a "microcant" in the latest Raceplate for sale listing that got me thinking about this. Anyone heard of that or know how to get it?

Thanks in advance for your insight!
