Would this work?

When I was building my diffuser fer the first iteration, I had single bungee cords holding it up. At speed, I got banging from the diffuser gitting sucked down, the air stalling, and then from the lack of suction/negative air pressure, the diffuser would retract back. This would repeat until I slowed down where the bungee cords were able to keep the diffuser in place. I would expect yer design to be similar and would probably function in the same way.
If you do go in the direction of a retractable floor, look at the rear door of the P-51 Mustang.
As far as yer choice in materials, you might want to look at Coroplast and aluminum angle to build out the floor pan with instead of plywood. Waterproof and there isn't a propensity to degrade with inclement weather. It will be lighter and more durable than plywood. It will last longer and be easier to work with and install.
I'm not sure you would want the upper part to be plexiglass as the suggested angle you have would make it rather difficult to see out of especially as the thickness increases.
