There's an old saying "it's always better to be judged by 12 than carried by 6".
You are a fool and deserve to have the book flown at you if, outside the UK, you deliberately plan to fly IMC on an IMC rating.
You are an even bigger fool if you get into a situation that you didn't expect, and you don't use IMC training to get you out of trouble if that is the solution which puts the aircraft and its occupants least in harms way. If you get prosecuted for this, tell the truth and let the local legal system do its worse - you'll still be alive to take the punishment, but the odds are any sensible legal system will not be particularly severe anyhow.
