Removing xbox live acconut from Microsoft account.

u need to make sure that your account is an adult acconut otherwise it would be rejected by the restrictions

The only thing switching Microsoft Accounts will do is change the account you sign in with. It won't transfer anything between the accounts. If you want to continue using the offline account, then you should join Live with that account.

There is no way to merge 2 accounts or transfer achievements or saves games from one profile to another. It would be nice if there was but unfortunately there isn't.

Would the switching Microsoft accounts thing work?
