I was thinking just that! My idea was you click an item and it becomes a random element of the same item type.. but I like your idea too!

May I suggest a shop mechanic, where you can spend points to purchase boons, such as a reroll, or maybe a specific attack type, etc.
Then you also have to consider your current points that you have to spend (thus temporarily decreasing your score) in order to potentially earn more points in the future.
