It could, theoretically, work all the way down to non-league Steps 4 and 5, where you encounter the first set of leagues where promotion / relegations isn't necessarily automatic.
In all likelihood, however, the Conference would continue with one less club, as they did for a fair bit of last season with the demise of Chester City.
I feel your pain, I feel your shame, but you're not to blame. She DID look like your wife from behind.
