If there genuine hight adjustable coil overs via separate hight adjustment, and not done through the spring platform, then whatever you adjust them by will be the amount the car rises by, if they are the latter then your also pre loading the springs so it a case of try it and see.

Roughly speaking...

change in height = change in length of shock * distance from E to F / distance from E to K :)

 

(in case the image doesn't link right - E is the inner end of the lower arm, F is the outer end, and K is where the shock attaches).

No it won't :) the coil over is not at the real end of the lower arm, so a ratio is imposed whether the spring perch is moved, or the damper is lengthened, even if there is full preload in the springs.
