Fixing An Acoustic Guitar Neck

This one happened yesterday, but I never thought about taking to Drooble with the issue until I saw the Repairs Community. But o h boy am I mad. My 9 y/o cousin is staying with me for about a week and a half, and I told him three days ago to NEVER go into my home studio. I can't lock it since I don't have a key so I just told him. But yesterday, I'm chilling on my couch when I hear the absolute unmistakable sound of a guitar dropping HARD. I was already pissed because every single one of my guitars is hung up on walls in my studio room. I go in, and I find him standing on my wheeled stool in the room, looking down at my old McGibney acoustic on the floor- literally the only object I have sentimental value to, being the first real guitar I'd ever had and given to me by my grandfather before he passed. I know these scratches will not affect the sound, but this guitar is my baby. With another acoustic of mine, I just sanded off the lacquer, filled the cracks with wood glue, and gave it a new finish. Unfortunately, wood glue won't blend with this colour, as you may see. Any suggestions how to fix it?
