I think I would leave things as they are. The weight of the dynamo is downwards supported by the 2 bolts below the crack and one above, so the weight of the dynamo on that casting is in compression at that end and in tension at the "inspection cover" end. The 2 long bolts and the 2 short bolts holding the casting to the crankcase stop the dynamo from twisting in the horizontal plane.
Filling the crack with epoxy will not add strength, may stop oil leaking out.
For my money, the casting had suffered an accident some time in its life. Keep the good casting and should the engine come out at some point for a strip down, helical the "stripped" thread in the crankcase.
