I would probably get new LX hubs if it were up to me. They have served well, and are very cheap if you just find an every day sale. In theory second relacings should follow the original pattern, and there are a number of different ways of going about lacing. So I would prefer to find the whole old wheel just to follow the pattern. I don't think the failures in the shell are a recent phenom, they have been addressed in the boutique hubs for a long time.
