Yer welcome.
If you're looking at a point where you recoup the expense involved in converting a cat system to efficiently convert oxides of nitrogen, I'd say that's simply not possible.
From a technical standpoint, you'd need
NOx sensors, some sort of
NOx-storing catalytic converter, and some way to automatically enrich the fuel-air mix to transform all of that stored NOx back into harmless emissions.
You're going to have to balance the increase in fuel economy you're seeing, with the fact that you're also emitting higher NOx emissions. You can offset that by using EGR, but be prepared to suffer a performance hit in the process.
