I wasn't sure where to post this question. Does anyone use a handlebar bag with their dropped bar bike/STI shifters?

I have an older L.L. Bean handlebar bag that attaches with straps, but it just doesn't seem to fit on the bike I have in mind. Between brake cables, shifter cables and the bike computer, it's pretty crowded in the area where the bag would typically go.

Is there some kind of adaptor made that would extend the bag out a bit and help it clear the cluttered area?
