Kohler Karbon deck mount would work but you might need to drill a second hole.

when i was looking for a lower faucet for my prep island, there were many single hole options. you might want to look at prep faucets. many of them have the same functionality as a main sink faucet.
i am not sure what style faucet you like, but i got the kohler purist for my prep sink. mine is not installed yet so i canot tell you if i like the functionality, but if i recall, it is less than 9" high.
HTH!

"it cut my water pressure in half"

Most likely any new faucet you buy will do this as they all come with the low flow water saver washer installed. You can remove this washer to increase the water pressure.

We have been very happy with this single lever one hole faucet, since about 2006. It comes in many finishes.
After about 5 years it started leaking at the swivel joint.
The faucet did not leak when shut off.
The company was very responsive both on the telephone and emails, but after sending a new cartridge (which did not fix the "Swivel leak") They replaced the faucet, (free of charge)!
Great Customer service!!!

Here is a picture of the faucet (Ours is Antique Copper) but it comes in many finishes. The faucet is just under 8 inches tall, alto the lever (which is in front) is about 10 inches high.

My Kohler Forte is less than 9" closest to the wall, although the handle curves upward toward you another couple inches.
