Sounds like maybe you don't really want a narrow bar, but feel like you should??
If you like to stick your elbows out to create space, then a narrower bar to be more aero seems a little pointless. If you are still going to stick your elbows out the small aero benefit of the narrower bar will be float away on the parachute of your position

.
That aside, if you still want the pretty narrow bar, but are still concerned that you wont be able to flap your bike from side to side, you do mention that you have good upper body strength - that should negate any reduction in leverage from going narrower.
A question - is your bike-flailing really for speed, or secretly part of your fear and intimidation tactic..
