Nothing! Because they already use that power, just not in public. They blatantly exercise their powers to extort judges/politicians/media to their benefit.
They’d be deposed, obviously. Thing is, the very act of deposing them would be an extralegal action, as all laws in the UK are established under the crowns authority. Legally speaking it would be the equivalent of a non-violent coup. Hence ceremonial by convention(de facto), rather than by law(de jure).
