Pull requests or patches are more than welcome, as I'm just getting familiar with the Tesseract training process myself. I've just pushed a few changes to get possibly-better output for the training_text and word/frequency files, but incorporating Latin-specific changes for unicharambigs may be something where someone with more domain-specific knowledge of both Latin and Tesseract will be able to do a better job than me. Due to the upcoming US holidays, I probably won't be able to do much more work on it this week.
