Killer Klowns From Outer Space Mask Molds and/or costumes?

[Chris Moliere]

Now that HHN's maze for the cult classic has opened up, I have considered making a Jumbo replica mask and costume, perhaps from some recast parts. However, details on the original pieces are very scarce. Luckily this post on yourprops.com has made raised my hopes, as the creator received access to the molds for Slim and Fatso. Are any molds still out there, and would anyone know who's in possession of them? Here's a picture of someone sculpting the Klown head I'm looking for the most, as I believe several other Klowns utilize the same head.

EDIT: Found a picture depicting of the masks I would like to hunt down the most.

I can’t help with the mold questions, but I am pretty sure that’s Mario Chido sculpting in that photo.
