Can’t you move the rack to a more sensible position ?To maintain correct steering geometry.
Could the forging be heated and bent into the correct position?

There’s a good reason why steering arms are forged steel and no longer than absolutely necessary
You can reduce the length of the arm (and the amount of stress on it and flex) by turning the tre so it sits below the arm. The original arm was forged steel, (or cast steel), and was triangulated to a point part way along its length, this was to reduce flex, I expect you will need to do the same.
I would make it out of a steel that has some resistance to bending, that you can weld without causing brittleness, or can take this out by heat treating. The Ford Fiest hubs of 30 years ago had really long arms - drove really soggy, lesson here, I think?
Oh, forget ally, of any sort, but maybe titanium, machined from billet.
Take a look at project Blinky....they fitted a Toyota celiac gt4 sub frame to a mini! Was really clever how they did it as I recall...made a template of the mountings etc.The only other way is to use an entire subframe assembly from another car.
