Can you draw out little "blobs" of color, with the sashing you want, and the colored triangles you want. Then stand back and take a look. Without drawing it out though, offhand, I think it sounds good!!
I've been collecting fabric for a DJ myself. Having a HARD time finding batiks in true grey (most are either bluish, greenish, or brownish). I want at least 5 different gradient grey's - the kind that read as solids - not the "printed" batiks. So far I have .... (drum roll) ONE grey that I like. Sheesh.
