If you have a large cast part you could do the same thing as you do with a frame or body panel now. As long as there’s a replacement cast part ready, it is lots of work in some cases, so it’s less “impossible to repair” and more accurately “cost prohibitive to repair”
I wouldn’t even say cost prohibitive. Imagine if you could just swap on a whole new front end after a car crash. Currently, it takes bodywork at hundreds of dollars per hour to repair damaged body panels while this could severely reduce that time and cost.
