Requesting mod to make NPCs 'Wear Costumes ' for holiday

I'd love to see a mod that makes NPCs actually wear costumes on the holidays where 'Wear Costume' is a holiday tradition. If possible, I think a mod that makes 'Wear Costumes' a club activity and a lot of the other holiday traditions club activities would be great as well. I also wouldn't be opposed to try to make the first mod myself, tho I've never made a mod before so I'm not sure how successful I'd be. I have a decent amount of experience with Python and I'm planning on looking at the tutorials on this site. But if anyone has any advice on where to get started when trying to mod this, I'd appreciate that as well! My game plan if no one wants to make this mod is to inspect the code, figure out what lines of code result in the change outfit action of NPCs (like when you ask them to change into their formal wear, swimwear, etc.), somehow connect that change to the specific outfits given to playable sims for the 'Wear Costumes', and then have that trigger during the holiday tradition 'Wear Costumes'. Does that seem like a reasonable approach?
