No point in rebuilding a 2.2 - it's not economically viable, and if your bottom end is good then there's really no point in not welding the key in place. What is stopping you from fixing it? Welding the key in place doesn't prevent dissasembly of the engine in any way - the oil pump drive is larger than the key/shaft combination and removal of the crank involves splitting the case so there's no drawback to welding it.
