Why not? You could easily use the following note tag structure: <increaseStatY: HPIs: 5, MPIs: 10, amt: 20%> and then parse the note. It's easy to understand and it fits in with other script customization. Personally, I think i'll be a lot more difficult for people to adopt scripts that use the customization styles from Ace and below. There's no built-in script editor anymore, so you'd be asking people to open up the JS files in their text editor, probably notepad for a lot of people, and then understanding how JS objects work. It just isn't as likely to work out.
