Can this be repaired?

I managed to crack the block on my 360 trying to remove the factory fitted upper oil galley plug (the idea being to install fittings directly into the block and do away with the factory oil line adaptor plate). The plug was in there so tight that burred the square allen head on the plug and eventually had to drill it and try an easy out, but the block cracked before it would move!

Could the cracked area be repaired by welding?

Or if not I'm thinking that perhaps I would grind the cracked area down and re-tap the galley, provided of course there is enough casting thickness in this area?

Failing either option I'll be looking for another block.
