I'm looking for insight on the best way to automatically add email recipients based on a relationship.

Here's the use case: I have an Organization contact type called "Account."  I have an Individual type called "Account Contact."  They have a contact-is / contact-for relationship, and they also have the same legal_identifier field in civicrm_contact.

When a user sends an email to an account, I want to automatically add the account's account contacts as recipients (or, better, give the user a checkbox on the form to include them).  How to do that?
Should I have modeled my contact types differently? Or, if not, I'm thinking the best way to build it is to use a form_alter hook. 
Any other, better ideas?
Thanks!

Hi. Sorry for not replying sooner.  An administrator would be doing the mailing.  The method will be Actions / Send Email: In this case the admin will enter the Account name or choose Accounts from search results, and somehow the system will find out the Account Contacts for that account (via the relationship) and add them to the recipient list.
Any suggestions you might have would be most welcome.
Thanks.
