it'll be possible to do something like that in the future where docker-slim will generate a spec that describes what your system and app package managers need to install. Using the standard package managers will be tricky for partial package installs though because it's pretty common that the app doesn't need the whole package. Even now docker-slim gives you a list of files your app needs, but the info is too low level to be usable by the standard package management tools.
