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.
