Short answer is no.
First, you don't just hang an engine on wing of a new aircraft and go flying - there is a massive amount of engineering that goes into integrating the engine to the airframe. Structures, fuel, avionics, hydraulics, electrical power generation, FADEC/instrumentation, etc. Rare is the new engine installation that doesn't require significant airframe changes to make it viable. Plus, a new engine installation triggers the Change Product Rule, so it's a major certification effort. If you started work today, you're talking a three to four year program before it's certified for commercial service.
Second, you're still talking a previous generation engine tech - the latest generation of engines is already several percent better in fuel burn (e.g. GEnx and GE9X).
Third, what airframe would it fit? It's too big for a 767/A330 (and the NEO already exists for the A330), too small for the 787/A350.
