Character customization / Head size adjustments

This is a low-priority suggestion for the character customization, once it will be implemented in the game.
I really want an option to adjust head sizes, for my own character as well as globally (if there will be NPCs), to enable more realistic head proportions.
This is a *huge* pet peeve of mine (and also others I've read on some other games) that might sound like a minor thing but: I despise "bobblehead" aesthetics in games and media. This is one of the reasons I couldn't play the "My Time at Portia" or "My Time at Sandrock" games, and also why I strongly dislike "Funkopops" or similar (with the obvious secondary reason that it's a wasteful use of plastic).
Thankfully the current headsizes are not *that* big, so I could live with it, but for something I will be looking at for possibly many hours, I'd rather have something to look at that I don't dislike ;)
