I have a very small, very old corner wall mounted sink with the faucet and hot and cold handles coming out the back vertical face of the sink. The sink does have an area (ledge) on the top. The hot and cold handles are round plastic cylinders and the spout is in between, about 1 inch out and pointing down. My baby girl can't turn the thing off and always leaves it dripping. Rather then rip the room apart, and try and hunt down a new midget sink, I was thinking about removing the old faucet and then drilling a hole in the top ledge for perhaps a single hole basin faucet. I would then be left with the 3 holes to somehow cover. Sound like a plan? Its porcelin and I think Cast iron.
