Imo, forget the 50%. Just fix it and let it go. Let everyone get used to the "real" repairs instead of taking the chance of messing it up even more and giving some more reasons to cry foul.
It all depends on communication. If a couple of weeks prior to Makeb's realease, they bring this up, that this 50% bonus will be off, then it won't be a problem.
Communication is a powerful tool.
