I think you could use it for that pattern. Try it on size 7s and you might get gauge. It may be a little loose, though I knit DK weight on size 9s and don't find it to be too open (not a tight knitter either, I have average tension). If it's too loose for your tastes, then try a size 6, and/or if your gauge is too small possibly make a larger size.
