Two Ideas/Suggestions: Skin Transfers for minions/enemies/environment objects, custom UI

I'd like to have the ability to replace objects in all environments (e.g. statues, trees, chests, crates, doors -- you get the idea) with other objects at will (and only for me -- not for other players, perhaps?). I'd like to be able to do the same with the enemies in the game -- Put all the gorillas and monkeys on a map in fire golem and regular golem skins in all areas, including endgame maps, or to perhaps raise the difficulty a bit, replace all mob skins with a particular one.

Also, as suggested by many before, I'd like to be able to change the art on the health and mana globes, maybe even move them around where I want them, along with the skill buttons and everything else in the UI.
