Package only UMG for non game apps

With every release Epic is reducing the package size for mobile apps. Latest lowest size is around 50mb. It would be great for non-game app development if we could be able to package only umg blueprints. I have some app ideas but I am waiting for much smaller package sizes. I know that Unreal Engine’s focus is not non game mobile apps but its waay easier with it than other softwares, at least for a non programmer like me.
