You're assuming Herb has a boss. (Technically correct, but not insofar as BattleTech)
Second, approval is Herb's job no matter what - whether 10 people sort and submit to him or not, it still comes down to him. Besides, the point is that there won't be writer-submitted designs without specific "design this to fit this art or this need" as determined by the line developer.
You might as well call it HerbTech. And remember that whatever works for you, knock yourself out and play - but what happens in your world stays in your world; it won't become canon even if it's so awesome it invented sliced bread. A shame...but BT is fun that way.
