It is the most obvious mod you can possibly do... Every achievement is time-stamped when its achieved on Xbox Live, by modding it they will all update on Xbox Live with an identical time unless you add them one by one logging in on Xbox after each achievement.
Also the crowns are matched up to your Xbox Live Gold time purchased. Having a 10 year crown when you've only purchased 2 years gold is so obvious you might as well just delete your account because you're going to lose it anyway.
You will always get caught - It's just a matter of time.
