This mod is probably already done, but I didn't care to look, it's an extremely simple mod that alters the Module Recipes as they were bothering me far too much and took far too long to build for my taste.

This mod simplifies the Modules to be less annoying and easier to manage, removes the previous tier requirement and re-works the Circuit Board requirements slightly.

If you believe this mod is too cheaty, then, well, click off, there's far worse out there anyway, I just made this because it was annoying me, and I felt like sharing it.
