is there a way to start with an existing model (XML file) and run the trainer in a way that would just _add_ my images to it?
no. to re-train it you would need the original faces (+your images) and the temporal stage cascades from the previous training.
many of the common faces I work with do _not_ get detected properly
there are a lot of alternatives to using haar cascades here, most of them more robust (like cnn based ones) or faster (e.g. pico)
we have an example for retraining / finetuning the dnn based detector here
