Will iOS backup include a paired Bluetooth keyboard?
Bluetooth pairing matches two hardware devices, so that pairing records are irrelevant if re-loaded on a different bluetooth adapter (on the new iOS device). Good thinking to get around a hardware repair - if you could somehow turn on assistive touch and try backing that up, you might be able to navigate - but I'm guessing that still needs some amount of digitizer functionality to restore the backup in the first place.
