Anyway, you're a good draft because you're a big guy. Handlebar width is determined by your shoulder size and spacing, if you go too narrow you'll create issues at the base of your neck and back. You'll be making a minuscule improvement in "frontal area," while causing a fit issue that will make riding your bike for any extended period of time impossible.
Personally, I run a 44cm (center to center) bar. And I'm 6'2", size 38 chest. If you want to get "more aero" learn to ride in your drops more; if you can't ride in your drops for a sustained period of time, your position on the bike (reach or drop) needs adjusting.
I'm putting you on probation from here on out; stop buying stuff for the next month (at least) and RIDE YOUR BIKE.
PS: If you put aero bars on your road bike, you'll never live down the TOTAL FRED status that will earn you. Don't do it.
