If you cast official GW parts with sprue goo made from official GW plastic would it be a tournament legal bit?

Took a lot of thin layers, but it’s a pretty promising test. Used an Oyumaru mold and did thin layers of pretty loose sprue goo and once I had a solid layer added it more liberally. Wish I still had a usable old sanguinary guard power fist to try it out with.

If you’re curious to try, be VERY patient with it, let every layer dry fully before applying the next one, or it will be riddled with bubbles.
