That is a nice pattern and would work any number of ways. I've got several groups of fabric that might work well (starts pondering). : )
The blocks look like they could be made larger or smaller without much trouble. A bigger block would showcase some larger prints that I can't bear to cut too small.
For a scrappy quilt I'm most comfortable with a limited color palette, as a true scrappy free-for-all is way outside my comfort zone. But that's just me, as many seem to enjoy the randomness.
