is it possible to create a multi-project template that references n number of existing projects and one new project?

The situation: I need to create about 40+ solutions that all reference 3 projects and have one project that is unique to each one. I'd like to create a multi-project template that does this, but from what I've read it looks like it's very difficult or impossible (related SO question, but doesn't answer开发者_如何学Go).

I want my solution to look like this (names changed of course): These three are used by all solutions created under this "family":

• MyCompany.Extensions
• MyCompany.MyProject.Tests.Shared
• MyCompany.MyProject.Scripts

This one is the one that makes the solution unique, 123, 124, 125 etc:

• MyCompany.MyProject.Tests.Unit123

Is it possible to set up a multi-project template that will generate this structure?

Solution files are pretty simple text files. Open one with Notepad to have a look-see. You could easily write a little program that generates them.
