Ya this would be one way to have the best of "most" worlds regarding adjust-ability in a suspension?
Your great benefit of adjustable coil-overs is having almost infinite adjustable for ride height ,spring rate choice, adjusting for different driving conditions, ETC.
But we may as well toss in a full air ride system so you don't have to get out of the tools and spend an hour changing setting on adjustable coil overs you can do everything while sitting in the car listening to the sound system. But a system like that is $3-4k.
Without going into the why's and not's , adjusting for a lower ride height for looks is not always the best approach to improving things in handling overall.
