Put a dragonfly detachable fairing on it. The dragonfly piece is good and will get you the look you want. The actual FLHT batwing wont go on at all unless you do the trees and EVERYTHING from there...too much change and a tad extreme.

mckays used to have a QD fairing kit available...don't see it right now, but you could inquire.
