You're not going to find anything that covers all the functionality of Cold Mac in 8hp. But you have some of that functionality elsewhere, and you might not need other parts of it. Maybe go through the technical map (https://github.com/whimsicalraps/mannequins-technical-maps/blob/master/cold-mac/cold-mac.pdf) and see what you really wanted from it. Anything you replace it with will almost certainly be easier to learn and use.
