As I mentioned, “doveadm import” allows one to provide an alternate source location, but “doveadm mailbox status” does not AFAIK, thus, a sample command would be wonderful.

if the user does not exist at all, you could create a dummy "restore" 
account, where you restore the data to and can use as any other user.
This would work for any existing user, too.

For me this is working, too:

doveadm -o mail_location=maildir:/home/user2/Maildir mailbox status \
  -u user1 all INBOX

shows the same as

doveadm mailbox status -u user2 all INBOX

but not the same as:

doveadm mailbox status -u user1 all INBOX

So, if you craft a good -o mail_location= and an "-u", which has 
access permissions on filesystem level (e.g. if you are using system 
users), it should work. Maybe, you need to specify "-o home=...", too.
