I don't think this would help. IMO, it's a money vs. effort thing. Yes, real research is hard, but if someone learns early on that the system can be easily gamed, then the required effort is relatively low.

Plus, there's the friction factor. Moving from undergrad to grad to post-grad to professor keeps you within an institution you know.

The game is this: get hired at a research university and pump out phony papers which look legit enough to not raise any suspicions until you get tenure. Wrap the phoniness of each paper in a shroud of plausible deniability. If anything comes out after you're tenured, then just deny and/or deflect any wrongdoing.
