Yeah 2200 is conservative, the hammerhead for example uses a 1/3HP motor but realistically runs closer to 1/2HP.
Even if power wasn't a concern finding a pump head approved for aquarium use, especially saltwater, will be extremely difficult and the cost involved will be far beyond what you would pay for a pump that was actually made for the job and uses a fraction of the power.
Reeflo also has a high pressure pump (tigershark):

Pumps up to 84' using a max of 1065W.
You may also be able to find a panworld pump that can go up that high but your options are limited when it comes to pumping over 25'.
