Why so much effort... Welding a bracket on takes no more than about 10 minutes (on the assumption it isn't to far gone...) It would probably work out more cost effective than faffing about trying to make something & having to buy the parts than the local garage would charge you for a 10 minute welding job...

Not all of us are welders - - - Or have access to welding equipment.
I've often cobbled up brackets using a U-clamp and various pieces fastened across one or both securing nuts.
