The best shape continues the curve & taper of your vestigal OEM mini-Kamm / roof extension.

You just decide how far you want it to extend (rear view considerations). And don't forget the sides taper in as well as the top down. EDIT: and you want a rounded top-to-side transition, not a squared off one.
