The exercise of creating a scoped app with a script seems fairly trivial if you look at the rollback for an insert into sys_app or what is included when you export an app into an update set.
We already have the application intake app and many features in AES I'm not familiar with. Maybe something that suits your requirements already exists? Other than that I'd think of the resources spent on building, testing and maintaining this vs. the quantity of apps being created.
