This is way beyond what can be handled on a internet forum. You need an experienced immigration lawyer FAST. You can't "prevent" your spouse from doing anything. Naturalization isn't an instantaneous thing and there's a strong chance such fraud will be discovered in the process especially if your wife informs on you (you can guarantee they will talk to her). Further, if they find you shammed your way into permanent residence EVEN after you are naturalized, they can take you to court to reverse that (it's takes a court rather than administrative action after you're a citizen, but IT CAN HAPPEN).

You certainly do ***NOT*** want to be caught making further INTENTIONAL FALSE STATEMENTS in your naturalization. You need a lawyer to go lever EVERY THING YOU PUT ON PAPER FROM NOW ON.
