I personally don't see it happening. EZY had A321's for a couple of years after they took over GB airways but chose not to order any of their own, instead just changing orders from A319's to A320's. Plus TCX also have their 752/753/763 (I don't think the latter two types are due to be replaced too soon) and a growing long haul operation, neither of which are going to appeal much to EZY (in my opinion...).
