You could use a Modulus reset for Co-op Bosses so that people whose boss levels are above whatever cap you set will just have a certain number (whatever cap you set, such as level 100) subtracted however many times is necessary to fully reset the level. There is a simple code function called Modulus (% in Javascript, not sure what it is in the language you use for the game) that outputs the remainder of the first number divided by the second number (Example: 152%5 outputs 2). As far as I know it's a fairly minor code insertion. Given this is more technical and I'm not sure how much of the coding side you work with, I would say pass this on to somebody who works on coding and see if they can experiment with that.
