since a in plaza store for accessories and such which i think is gonna happen i think it will need more stuff to it other than hats and clothes
(this place, or at least from what i and others have heard its planned for a clothing/accessory store type thing)
so maybe in there could be the bone modifiers (the thing from GMT that allowed you to get a big head or giant hands) and maybe the ability to buy custom animations (such as zombie walk animation or lego man type animation with straight legs and arms)
and also glowing player models used to be a thing which a decent few people had and liked
so maybe normally you can be restricted to normal colours when being able to change colours on default or recolour-able player models but then you can buy a glow mode (lets say for 50k units or something) that allows you to toggle a option to make the colour glow
(this is different to the milestone, the milestone i a outline glow not a bright player model)
And i also thing changing the material overall would be cool. like your player model but it has a select amount of materials you can buy (around 10k or up depending on the material) and then place on it.
ignore my shitty photoshoping skills but this gives the point, you can select any material on the workshop model and apply the different materials you can have such as the Burning zombie, plant/leaf material, gold (maybe this would be a unlock-able material for getting certain achievement like winning a jackpot)
