With a normal lock, will that then help? It takes 4 instead of 3 seconds? Lifting over is lifting over, it should almost be irrelevant how far they slide into the "clasp".
No.
Just look at your windows, how many millimeters the lugs are in the frame.
Sorry for my technical jargon, but as a professional crime scene cleaner I have seen a lot of lugs. Most grip barely 3/4 of 10mm. The lever must first overcome that on rigid plastic. Often a second tool is needed; many trips, however, only bring one.
