Is there any way to accomodate multilanguage email as well as the flexibility to incorporate BCC&CC?

We have a requirement to send out multi-language email to customers (conditionally). customization of BCC/CC is also a must have (which can be done via using standard email action but it does not allow the association of Email Designer template with it). Currently we are sending out the emails by defining the notifications on step transition (as it supports associating Email Designer Template), but it does not give the option to customize CC field and BCC option is not even available. Is there any other way to full fill the requirement?
