That sounds ideal for adding a Kammback, or even a boattail.
The Kamm I made for my previous Pug307sw reduced fuel consumption by 7-8% in the 70-100 km/h range, based on testing at a steady speed.
But that gain almost doubled, because better aero allowed for much longer coasting between pulses. If you have long but not steep downhills, you may also want to add an engine kill switch to save more while coasting.
