I want to do that to mine as well. I removed the springs earlier this season to replace the air bags (it seemed easier than trying to jam the bags through the small hole in the lower control arm). It's not a horrible job but as you said it's not fun.
I need to have mine weighed before they will sell me springs, they said. I haven't come across a 4-corner scale yet - only front/rear.
