Never attempt to intentionally invoke Cunningham's Law with a solution you wouldn't be happy with. Which is a more specific form of "never propose something you wouldn't be happy with", or "be careful what you wish for, because you just might get it".
Corollary: be careful what other people wish for.
That seems more like a hiring problem.
The problem was they hired the first candidate, figuring they could get a replacement when a better one came along , but the first one got entrenched.
It started as a hiring problem. Now there's still a hiring problem, but there's also this one, which is unrelated. Both should be fixed and, unfortunately, neither has an easy or comfortable solution.
