I think there is a thread on here where someone modified an existing solo rack (or short bag rack), and did a very nice job. That's got to be easier than making one from scratch.
Edit: you beat me to it Poppa.

I think it was this one (or similar). This is not made to fit Valks.

BTW, Custom World International (in Quebec) makes a lot of unique items, including solo racks that are actually flat and not curved. But they are expensive, and the site is (or used to be) in French, and is hard to navigate. No idea about Valk fitments.
