i would imagine, that already exist...i the sense that one could use a SPACER for the coil setup but place it on the bag set up...if they are coilover type and not the shock style.
in most cases, when you look at lifts, a 4" start the transition to HARD PARTS being replaced, this relocates mounting points to a distance further from the vehicles frame, thus creating a higher ride height. do you gain travel ??? usually not, but you do gain height. level kits started as just that, a means to LEVEL the vehicle, either by a slight raising of the front, or lowering of the rear.
but lie everything else, people wanted more for less...hence the multi inch level kits, now named suspension lift. problem is, more is not better...and then add STANCE by heavily negative offset wheels...and your ball joints are way over stressed.
how may have you seen with castor that cannot be corrected simply due to leverage against the ball joint. VERY DANGEROUS to have this setup, and dont even get one started on wheel spacers....
best bet is to speak with or contract known professionals about the lift choice and wheel fitment. you wont see Carli, Thuren, or any real SUSPENSION SYSTEM company build a vehicle with that style.
