I think the focus on William here is a good choice. Seeing as he hasn't got The. Rat. in your universe, his actions are the most impactful.
To be frank a lot of Michael content will overlap with the stereotypical Michael aside from... noah.... Unless there's one that shows him being competent as the mc of the fnaf games or assertive as 'a Fazbear Entertainment Franchisee' restaurant owner. (Gaslighting those lawsuits out of existence takes balls lol) Generally stereotypical Michael is someone who is 'bullied' by his siblings and curls inward as an anxious meow meow (i think lol. i don't really consume that content outside of parodies. Could be mixing that up with those 'soft'(?) au thingys.)
Love your characterisations by the way. The way you portray the characters in your au is a breath of fresh air. <3
