Previously when I was using Postfix to deliver the mails, I could change the maildirloc in the DB - but I’m not sure how to accomplish this with dovecot LDA.

I'm using Postfixadmin to manage users and have server alias-domains. 
All mail sent to an alias-domain is delivered to the other domain. Quite 
easy if you've got postfixadmin already setup.

Otherwise I think you could configure virtual_alias_maps in postfix to 
something like hash:virtual_domains

virtual_domains:
@example.net    @example.com
