I have to correct myself. Changing the angle of P1 does not change the ensemble detected by P2. Only the fraction of photon 2 whose peer was detected at P1 changes.
Yes, and that is exactly what the detection loophole is all about.
In the newest experiments, they basically managed to detect every pair of photons emitted, so this kind of mechanism is ruled out experimentally.
There is also a substantial literature on the detection loophole that you should familiarize yourself with.
