ItemOptionSystem plugin improvement

Is it possible to add more parameters for the plugin, such as max level, that would allow the optionvalue to increase depending on the level of the item. Also Luck and Addition option, as on some items this parameter is considered as an option.

I also have an idea for new options:
Skill Range decrease, pvp option which would work with chance for a while
Remove Buff (randomly) pvp option when attaking an enemy  allows you to remove a buff from an opponent. 
Push an opponent back a certain distance when attacking them or when someone attacks you.

And lastly, probably a crazy idea, to create a plugin that allows you to assign monsters any of the available skills (characters skills).
