Custom 1k hats are already very time consuming and players do message admins repeatedly asking when it will be uploaded, was it reviewed yet etc. Similarly, although it's just a minor edit, players are very likely to wait for a day or so then start asking why their hat isn't uploaded yet. There are different time zones and everyone has a life outside the game. The gfx admins aren't online 24/7 to attend to your needs and wants so overall, just my opinion, hat edits shouldn't be allowed.
