I'm no lawyer, but I don't think judges overlook constitutional rights just because an officer "found something." In fact, I believe there's an entire industry of defense lawyers that exists because judges don't overlook those rights.
From another vantage point-- if officers can invent reasons for searches that pass legal muster, then what does it matter that parallel construction exists and has a constitutional loophole? If it were really the case that there's an epidemic of invented reasons for warrants then parallel construction would improve the status quo by reducing the number of dubious warrants, leaving only those that "find something."
I'm playing devils advocate here to fish for a legally competent response...
