Wow. I'm glad things worked out for you and your daughter as well, and it definitely reassures me that you're going into this with real-life knowledge and experience to draw from, as that means your fill will be as realistic as possible for MCU-based Mattie without going full-out Miller-level grimdark ridiculousness in the process. I'm very happy that the endgame is undefined for now and entirely at your discretion, part of the reason I prompted instead if writing is that I wasn't sure how it would end in my own vision. That and rl problems are keeping me busy. Good luck, take your time and enjoy!
