In a word, no. Magnesium alloy = extremely difficult to weld, can catch fire if not done properly, hard to extinguish if it starts burning (white hot flame that can burn underwater). Some people do weld these cases behind #3 cylinder, so it can be done, but only by someone well-equipped (proper type extinguisher) and experienced with ACVW cases. A crack due to a collision is very difficult or impossible to fix correctly so it doesn't come back. You'd have to grind out the entire crack and follow it everywhere it leads, until it is completely eliminated. Then you'd have to weld it all up, back-filling all the ground-out areas. The you'd have to re-machine or re-drill all the affected areas. The welding process can easily warp the case and make all your eforts for nothing. See where this is going? IMHO, it's cheaper to start with another case.........
