I agree with the comments above, I think this direction is a mistake. Furthermore, I'd be willing to bet that the pool will need significant maintenance and repair when you decide to re-open. You have empty water pipes with standing (stagnant) water in them. A pump that isn't pumping. A pool designed to be full of water (and pressue) standing empty. Then large point loads on a relatively thin concrete surface not designed to carry a load. It's a very creative project, but misguided.

To continue to beat the dead horse, why? Fence or safety cover is just as effective, and still allows you to enjoy that very nice pool. Furthermore, any kid old enough to be in your backyard unsupervised should know how to swim. As my son's swimming teacher liked to say, swimming is the only sport that could save your life.
