I think the hole in the tube will be fine now that you have welded it up. The bronze looks more concerning to me, if that's what it is. I might be inclined to go back and grind most of that out and do a better job of welding it up. Then, if you still aren't comfortable you could build some sort of a truss like us off road guys do. A back truss is very common on the 9", but you don't have room there. With the butt welded axle tubes a truss really isn't a bad idea anyway. With the fab you have already done I am confident you can make something work and look right.
