Apologies, I just looked again and its the small bolt hole you have fractured, probably be fine with alloy welding, for some reason I had it in my head it was the big un that had cracked, probably because on mine it was the big bolt lug. I am bound to still have the forks in question and if needed can dig them out and sell you the spare lower leg provinding it passes muster, ie no stripped threads etc. One word of warning though, with so many project machines I am inclined to take an age to find bits or even forget why I went out to the shed and get distracted by rusty things so may need reminding.
Regardds bleeding the brakes, my preffered method is a bit of clear pipe, comes with most bike batteries for free and a big seringe to squirt fluid up to the master cylinder from below, I had several that would not bleed the conventional way , this way got it moving, then I suck the fluid back down from the master with the seringe until it runs clean and free of air bubbles.
