Non-traditional control for three hole bathroom faucet
An Escutcheon or Deck Plate can cover the outer 2 holes, allowing you to use any 1-hole faucet you like. The downside is that they can be quite large, and the selection at 8 inches isn't that great. Example product.
(Whether this would fit with your preferred style is a different question.)

You could also have a 1-hole faucet, put a soap dispenser in one of the holes, and a simple cover over the third. That would be less than ideal, but so would an escutcheon, and it might work better for you.
