Asking the coil springs to do the lifting may be a lot to ask of the springs and the space they need to be in. Not so much by work but stock and after market springs are meant for a work load and need to work in the given/confined space. Suppose you could use coil spring spacers, but I can't tell you how the ride quality will be affected.
If you don't find springs which are taller, you may find springs which are so stiff as to make the ride less enjoyable. I suppose you could use stiffer shocks to help raise the ride height, but in my limited opinion, you might be better off going back to stock spindles.
However, others will chime in with more/better experience.
