I have used movers & shapers on a BSPro, without the base- I did the same as you and bought them without realising. This was my sandwich from the bottom up:
2x Clear Plates
2x Mylar Shims
Crease Rule( the rubber mat)
Sometimes I've needed to add a thin cardstock shim to this mix. I have also been able to cut 3 layers of paper at the same time.
There are some other recipes on my blog page for Cuttlebug/BSPro.
