Time, money.

They don't need to redesign the wings to accommodate the newer, larger engines.

There's only so much room for the landing gear. Larger diameter engines require longer landing gear. Increasing the space given to landing gear requires changes to the wing box. Changes to the wing box is fundamentally a wing redesign.

Which is why the A320 is designed to be loaded with conveyors. This means it has no problem accommodating an even larger nacelle than the 737 in a regular position instead of the up and forward the 737 Max resorted to. Even the previous generation 737 was running into this issue and that's why they went with the distinct oval nacelles.
