Alright, lets start with the length of each starting with the MOL. Look at the length from the eyes that the "swish" at the top of the head is.Not only is it about the same length as the Kaukau, it also has the same bump down the centre.
Now lets look at the sides of the masks. Pretend to cut off the spikes from the sides of the MOL. This part matches the kaukau in the exact same way the "swish" at the top of the head does.
Now, look at the front of the mask. Not only does some look built on and cut out-but the size from left to right is almost the same as the Kaukaus.
The only difference between the two in my eyes is that, the MOL is an updated Kaukau. It has a larger mouth, eye holes, and do on.
