Inheritance system for folders in Windows 8?

Okay, here's the scenario.

I have a base folder "Base" that has a blank, multipurpose template. However, this template is 12 gigabytes. I want to be able to have an inheritance system where linked folders have their own content, but use their parent folder's content when they can't find it. Say I have 3 different projects "A", "B", and "C". I want A, B, and C to all point to Base. However, I want to be able to overwrite certain files in A, without modifying anything in Base, B, or C. And maybe I want to add a few files in B without them showing up in Base, A, or C. That way, I can still have all the functionality of Base, but with only the file changes taking up space and the rest only needing to exist once (in Base).

Bottom line, I want a folder inheritance system (or a 1 way symlink) for explorer.exe on Windows 8. Thanks.
