Not as easy as it might sound. Don't forget that KISS has the extra lights in the head dirven by an aux. lamp driver. Also KISS has a different transformer than the 'standard' for the era. When playfields and backglasses were reproduced people looked at doing this, but I am not sure how many actually went ahead.
Should be achievable, but a lot of work - you would probably need a KISS on-hand to 'copy'.
