2slick,
I wouldn't worry about the square tubing. If you go with a live axle, I would be looking at mounting the hangers to the round tubing. Hopefully the round tubing has a thick enough wall thickness to support welding on the hangers. Then you could relocate the square tubing in between the round tubing to tie the parts together. Also, if you are worried about flex in the round tubing, you can weld a piece of angle iron (V Down) on top of the round tubing and this will strengthen it substantially.
