Keep producing the A320neo, A321neo and A321XLR (at ever-increasing price, of course) for as long as airlines want to value commonality with their existing fleets above anything else.
Or, see what good thinks Bombardier made with A220 and integrate those things into the existing design to maintain commonality and CCQ with A320/330/340/350/380.
Airbus is not stupid enough to throw away a mature, well-designed and well-tested product with millions of hours of safe flight, just because they purchased a product line for free that
might be slightly better than one of their current products.
