My Apple ID is a 3rd party address. The ID does not have a @icloud.com mail account yet.
If I turn on the @icloud.com mail account by creating a new a new @icloud.com address, is it possible to use this new @icloud.com email address to replace my 3rd party address' Apple ID?
Based on what I have read, I suggest you leave your Apple ID email address as a 3rd party email address because you have more flexibility if you need to change the email address. For example, if the Apple ID got compromised, you can change it to another address. I also have read of many people who were locked out of their accounts when they forgot their password. Since the recovery email address is the @iCloud email address, if you forget your password, you also can't access your email to get emails from Apple to recover your account. You can set a rescue email address, but for some people, this hasn't worked.

If you create a wholly new Apple ID, you will be unable to transfer existing purchases, subscriptions, and music to that Apple ID.
