The problem is whatever is the original is reproduced in the molding. You are missing a chunk of the flange and that would be reproduced and you don't want a missing piece of the new part.
Completely disassembly of the old part. Even removal of the brass bushing then scan the part. It should be a simple matter to remake the part on a CNC machine with the missing pieces remade from a stronger grade of material than the original.

You just bondo the old part first. The problem I see is the temperature required for the molten metal for a DIY project. AL is not bad, but going up from there takes serious heating equipment.
