[HO455]

X's3 with Overdriven! Although I may not actually poop on your idea I know it isn't at all practical. It would take you at least 60 minutes to get all your bags pumped up using that kind of compressor (15 minutes per bag) It is likely you would melt the compressor before you were finished.
Here is my Burban on bags sitting on the bumpstops and on the bags with the bump stops cut off. (They were removed when I bought the truck and I have since reinstalled them). And the final photo is a comfortable ride height for long distance highway driving. I can go a little lower around town and still be safe and comfortable (About 1").
I hope this helps if you want to go lower it will take the modifications previously mentioned.
