Just don't tell the wife until the fry are in the tank. Then she won't be able to say anything!
Of course, that still doesn't solve all your problems, as the 10 gallons still wouldn't be near enough space for the fry long term. They are going to need another permanent home. Have you looked into how you will deal with them when they get bigger? Do you have friends to give them to, or a LFS you can take them to? (This is the curse of livebearers! )
