You know that all the public universities already do this right? The books, including salaries are 100% public in many states for (at least for the state universities). Why do you think they are so much cheaper than the companies and Private PIs that do get grants? (BTW that thing you wish for exists: look at SWRI for example). The only requirement to get grants is the ability to convince the grantors that you can do the work more effectively than the other applicants.
