I believe your question has two parts.
<> Can you repair the fork? Yes it can be done. However there would be a huge liability exposure if you do an in-house repair.
<> Should you repair the fork? Maybe..
depending on whether the factory can reman the fork. I suggest you contact the fork mfg and get their suggestion. If they can reman the fork it will be as good as new. If the factory can not reman the fork junk it and buy a new one. However, be prepared for another problem in the process. When a pair of forks have been in service for awhile they will develop a "sag". When you put a new fork beside an old one they will likely not hang the same. The new fork's tip will be higher than the old one. In some applications this is a major problem.
