*It looks like your roofline already has some down-sweeping camber,setting you up for some boat-tailing.I don't know if lofting the roof to get more would pay for itself.We have very limited data on this one.
*Any boat-tailing should help if you can tolerate the added length.
Here you can see some wind tunnel-derived values for a van-type vehicle,including boat-tailing
Member orbywan has seen mpg success with boat-tailing to his Ford Motorhome
Softening the edges will kill vorticity,lowering drag,as in this GM Optimum boat tail
The ideal,is probably the inflatable tail,which deploys automatically,and stows automatically
