You seem to have a little bit of almost everything, and certainly a lot of fresh/citrus/aquatics. You don't have much by way of 'formal' type fragrances, either.
Perhaps some fougeres or orientals would round out your collection - Ralph Lauren Polo (original or Modern Reserve), Chanel Egoiste, Calvin Klein Calvin, Aramis (original, 900, Tuscany, or Devin), and Guerlain Habit Rouge.
You could also use a masculine/patchouli, such as Givenchy Gentlemen, and you could use a vetiver or two, such as Guerlain Vetiver or Lanvin Vetyver.
None of these are niche, but I don't know what the availability is Bogota is for all these brands. Hope this helps.
