If you performed a backup of your device you may still have the new messenger. DM consideres it a 3rd party app and if you backed up your 3rd party apps then you be able to reload it in application loader in DM.
I have a theory,
If someone you know has backed up their 3rd party apps and sent your a ziped file containing their ALX/cod files from the temp folder it should work.
I have not tested it out to find out if it works. But in Theory.
