You are saying that there is no genetic component to personality? That's dumb. Are you saying there is no genetic component to facial features? Also dumb. Are you saying that there is no crossover whatsoever between the genetics that govern facial features and personality? Also dumb. There will be crossover above 0, it would extraordinary if there were 0 crossover. So there is likely some small correlation between facial features or skull shape and personality. How big is the effect, I don't know. The problem here is that you are judging the value of a person based upon their personality, not that their personality might be bound up in some way with their genetic makeup.

You've missed an angle - the causal link between genetics and personality is completely overwhelmed by the non-causal correlation between genetics and social status.

These models aren't going to pick up the correlation between facial structure and personality, they are going to pick up which families are high status and which are low, then provide the same pseudoscientific justifications for discriminating that people have been deploying since the dawn of pseudoscience.

Basically, these models are going to mislead people into thinking that a non-causal correlation is causal.
