This is a cool idea.
I was tempted to comment that there’s no evidence that you can make anything complex out of dark matter, but it turns out that some physicists hypothesize that “self-interacting” dark matter could bind into something like atoms and molecules, so carry on!
It's worth noting in passing that “some physicists hypothesize” is entirely compatible with “there’s no evidence”; this should not be disqualifying for science fiction.
