Floor storage

Some of you have already welcomed me in the newbie thread, thanks for that. Now come the crazy questions.
I was thinking of building a floor from out of 2x12's to create a large storage area under the floor. It would be divided into atleast two sections, one accesable from the inside and another from the galley. I'm thinking that the popup tents would fit perfectly under the galley in that area behind a cabinet door or in a large pull out drawer. Maybe even a couple pull outs on the sides.
What do you think? Did I convey my idea well enough? I realize this would casue the TD to be approx 5 fett tall and may require laminating ply to get correct size, but do you think it would be worth the effort?
I have more crazy ideas like this but I will feed them to you slowly.
