[Inkscape-user] Puzzle with a puzzle

Nicu's fantastic SVG clipart resource includes a Rubik-style cube.

I have a puzzle. What is the simplest set of operations which can allow me to recolor the squares (combining paths, breaking them apart, turning into bitmap, back again, filling derived paths etc.) I guess I need to decompose all the overlapping shapes into line segments, build them into shapes then somehow fill them.

So I have an unusual puzzle - how to mess up a perfectly solved Rubik's cube. Surely it can't be that hard. People on this user list are BOUND to know how to do it, and I'm stuck.
