That would need something specific to run on all of them. Plus there would be no way to keep it being the only thing on the devices without wiping much of the stuff that is on there. I don't see a simple way to do it.
If that is the only thing you want running on it you really need to get in touch with a creator to see if they can make you one specific to your needs. Especially if you are wanting this to be the only thing on the device. They would then also be able to help you access as you wish.
