Sure,
@Elliandra, that's doable. It's simply going to be very hard to remove such a monster, a heavy monster at that. You might slide a long, semi-flexible blade all around the root ball to free up the root attachments to the terracotta, then have a couple of strong people help lift the plant/root ball while another is pulling down on the pot to free the root ball. If the top of that pot is more narrow than the middle of the pot, it's almost impossible to remove the root ball without destroying either the root ball or the pot. Ask me how I know...........
