Over-Axle Conversion?

Has anybody ever considered or gone through with converting their worn-out rear leaf springs to an over-axle application as an inexpensive temporary fix for a sagging rear? I have a couple of perches...seems like I could just weld them on top of the axle housing and flip the shock mount plates and get an instant 3+ inches of lift. I'm FLAT broke right now and I'm beyond tired of scraping my headers everytime I hit a slight dip in the road.

Any comments? Thanks!
