No but that's a good idea. Acorn has a really nice front rando bag, but it costs $150 and is larger than I need right now. Topeak also has a nice handlebar bag that might work. I just wish I could look at one in person to see how it might attach, as I don't want to mount it on my handlebar. Might as well use the rack since I have it, plus lowering the weight should affect handling less.
