Alternative database sources

[PRGfx]

I like the package for its conveniences, however in some cases I can't use it because access to the flow commands to fetch the "real" database is not intended/restricted/...
I would imagine an alternative way of downloading a database dump from a different source and then proceed as before with resource proxies and stash options.

Is there any way I could do this with this package or would this exceed the scope of this package?
