I'm not sure that is possible (notmuch db, without a Maildir). As far as my understanding goes, you can inject a message in the db just fine. However retrieving/display is done by actually getting the file from the mailstore (Maildir). To get your proposal to work, you would need to work out a way to "reconstruct" the whole message from the database only. In theory, this should be possible, but I have no idea how one would proceed.

On top of this, not having a Maildir would mean cli tools will get confused; although this might be okay in principle, but library only notmuch system with broken cli tools would be pretty non-standard.
