For some reason this stuck in my mind, now I have an answer you might pursue.
I think the deluge solution might have some merit. Often I think we forget to separate the 2 distinct functions of a sprinkler head. First and I do mean first it is a heat detector. Second it water distribution valve/device. The Code deals with both - heads within 12"....3x rule... I don't see a reason you can't get equivalent detection from some other device. Could even be a smoke detector as they are faster than heats. Next make sure the head distribution covers the floor with the minimum density. There isn't even a reason to locate the heads near the ceiling as long as the distribution is adequate. Probably a few, 4' or 5' above the floor would be adequate. And with a deluge you are getting extensive pre-wetting far in excess or standard wet, dry, PA systems. Now this isn't a sprinkler contractor solution as it is outside the Code. Will require a PE to be legal. And obviously AHJ agreement.
