Yep, that's what I was imagining but with a narrower bar for gadgets, not to hold on to, and necessarily lower since I don't have that much stem left. Big question for me is how much does it get in the way if you normally ride on the hoods like I do.

It would probably rule out the trekking bar/aero bar idea unless you put a chin rest on it or a pad or something. So it's two independent questions for anyone who knows about the trekking bars.
