Here's an interesting requirement. Has anyone had a request to have emails/templates built in SFMC then exported for use in another system?

So marketers could build either an email (to be used as a template) or a template in the SFMC because that's where they are comfortable. Then an external system can either take an export (not sure if this is possible, I was told Salesforce can do this) of the code or retrieve the code through the API and then use this in an external email send through a separate system.
