Totally possible. I think Habitat by Chef tried to do an easier version of this, and many teams on Golang stacks are effectively doing this with Docker today (images with nothing in them except the app). The issue is that if you're an engineer coming up with the toolchains for your packaging and you say "I opted to write scripts for packaging our stuff as tarballs and running the app in chroots", your lead will ask "why are you wasting time on that and not using Docker?" And it will probably be a difficult conversation.
