Hi,
Sorry, this is not possible. Email tokens are registered per email, the allowed email tokens can be found in the email itself.
For example, if you check the email: You have been removed from the course, then it has only 3 tokens, refer:

No other token will work for this particular email because only these three tokens were registered for this email.
Similarly, every email has it's own token and you cannot use another token in some other email.
