Do you have any recommendations on which Windows/Intel tablet is best for this? I've been thinking of doing the same.

Edit: It will be easier to get a device with UEFI firmware. It seems possible to replace the firmware with a manufacturing tool published from Intel. But i haven't looked into that yet. I might try at some day to compile TianoCore or coreboot for it. Getting fastboot to work for Android seems possible too.
