Air Weight Distribution Hitch

OK so here goes. I thought this would be the most likely place to post this because it directly relates to hitches trailer and towing. I was wondering, what if, a weight distribution system was to use an air bag instead of the typical spring bars. The system would still function in the same sort of way as a typical spring bar set up but instead of having snap up brackets it would use a frame mounted air bag nestled in the V of the trailer. So what is the difference? well I was thinking that there would no longer be the need for a big pry bar and leveling up could be done with the flick of a switch. Thoughts?? Yes I know that it would need a compressor but for those who have the needed equipment I though, what the heck.

This is just an idea but I thought I would through it out there. Very crude Diagram below.
