I'm going to revisit yayahud.
It was never really *my* hud. I updated it from takyahud for a couple major TF2 versions, but I didn't customize it and didn't fully like how it looked.
I'll be merging Hypnotize's updates and working from there. Not much will change ingame aside from the scoreboard, but MvM and the main menu will definitely see some work.
Expect a darker main aesthetic with a small number of bright colors to make it stand out.
