[@Mae] Ultimately it comes down to you as the GM, and how many players you think you can handle since the cast is already very big. For me personally, I wouldn't mind it. I can also (with your permission) tweak Jada a little bit to better allow a character like Saya. For example, since she lives on a homestead it's possible her family keeps livestock - and she was expected to continue the family ranch until Brisk reopened the guild. Now that she got a job with the guild, she takes this chance to get closer to Boro and Saya in order to learn magic - making her more of a novice but also playing up the possibility of an apprenticeship when the country girl learns she might have some magical talent.
