Drill some rosette holes to anchor the new part, a beveled edge at the open end for welding, heat the repair hole and insert he repair part , weld .
Just a thought

And unless you can weld deep enough, the insert will not hold a 100 Nm torque and pull out of the hole. This is not the best place to take chances. Since the whole car is upside down, just do it the best way.
1. You can use two Timeserts, one of the right size and one larger to fit into the hole. the problem with this method is the larger hole may now weaken the wall of the hole so it may not hold.
2. Cut out the back of the bracket, weld in the nut, and refill the bracket as much as possible. Smooth it out and paint.
