First, since you have plan upgrade your axles, then fix what you have for now. I am no mechanical engineer to be able to sit here and explain the heat treated compromise that has been placed on the metal in that area but I have over the years fixed stuff like that and it held up. I would grind the welds up, straighten the bracket, use scrap metal to make mini skids (that what I have now) to add support, then weld it all back up. and send it!
