Leon,
  You're not going to like this, but my advice is to remove the tail and put it back on straight.  Putting on a bandaid like you're talking about is still going to leave you with a crooked tail and possibly permanent yaw.  A few builders are pulling off their skins to straighten bent wings, so it can be done to the tail.  The best option is to do it right.  It'll be a pain, but you'll sleep better at night knowing you fixed the problem the right way.
