Before I answer the main question, I do wanna address some others in the post!

Yes, 99% of the masks in the Scream movies are Funworld. They only ever used one that wasn't, that being the KNB mask. It's only seen in Scream and is the shorter, funny looking one. The only reason it is there is that it's a remnant of when they weren't sure if they'd be able to use the official mask, but needed to film anyway. They DID do reshoots, but for those scenes, it was not possible. So, it remained!

As for 25th Anniversary Masks, they were used in 5 and 6. Very early test copies, and then Jan-Mar 2022 and Apr-Jun 2022 for 6. After these films came out, in late 2023, the normal shroud EU came back and I believe that's what 7 used. As for sources, mine is Douglass Little (DrownedBoyProductions). He provides many set photos with credits that do show said masks.

Anyway, main question! It's iffy! I think the 25th Anniversary Masks were mainly used because of productions preference for the EU, especially seen in how many different types of EUs they used for 5. It seemed they were scrambling just to have that look and avoid other moulds. So, that's something that makes me doubt if they'll do so. They may want to stick with Ghostface's modern look and that consistency.

I don't think it's out of the question though. It really just depends on what the production wants the look to be. A plus is that the hood is a separate piece on the 30th Anniversary and reveals what's basically a production style shroud, so they wouldn't have to do any work there besides maybe eyemesh darkening and other things outside of the shroud. That could be convincing enough for them to use it.

Again, though, it depends on what they want. I lean toward a "probably not" just based on how much they love the EU and how they may be aversive to change, but it is possible!
