It it possible to share a Dovecot passwd file to use it with Postfix's virtual_mailbox_maps?

I run a small Postfix and Dovecot server with only a few mailboxes. All are virtual via Dovecot, there's no local delivery. Caused by the small number of users, I simply use plain text files for the password db and have configured Dovecot like this:

passdb {
    driver = passwd-file
    args = username_format=%u /etc/dovecot/users
}

The users file has the syntax

address@domain:{HASH_ALGO}somehash

To prevent backscatter, I set Postfix's virtual_mailbox_maps like that:

virtual_mailbox_maps = texthash:/etc/postfix/virtual_users

also using a plain text file, but this one has a different syntax:

address@domain somestring

Now I wonder if it's possible to directly use Dovecot's passwd-file for Postfix's virtual_mailbox_maps? Something like proxy:unix:passwd.byname?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
