Very beautiful ship, Mr. Howard. I wish my first, or second, or third, etc. looked as nice
A better method to deal with strong winds is to devise a way to remove sails (or reef or furl them). I use sail removal, and it works (as is should, after all, as sail reduction is the way real squareriggers deal with high winds). Study paintings of real ships to learn which sails to remove as the wind picks up. A great book on squarerigger practice is John Harland's "Seamanship in the Age of Sail." I remove topgallants first, then courses if necessary, following actual ship practice in the 1800's. In the 1600's, the sequence would be topgallants, then topsails, then courses. 1700's practice varied.
The problem with simply adding more ballast (or giving it a longer lever arm) is that it leads to more strain on the rigging, particularly in gusts. If your ship is heeling excessively in light airs, then by all means lower the ballast. But as a method to make your ship more gale-worthy, I'd not recommend it.
One further advantage to reducing sail is that it changes the look of your vessel. After you've collected many photos of your beautiful ship at sea, you will probably appreciate the possession of a varied collection
