I’ve seen other people thinking that, and I’ve even considered it myself, but I’m not sure if that works out chronologically; if Axelford’s project is accepted, it would be announced in early 2023, and then I don’t think it would actually release until mid-to-late 2023, well past the predicted release date for the GWP.
It becomes even more chronologically impossible if the current images turn out to be accurate, since that would mean that the GWP was in production well before the Ideas project even hit 10,000 supporters.
So unless Lego has so much faith in Axelford’s project that they made promotional material for it before it even achieved support, and will have a model ready for an announcement-day release, I don’t think this GWP can be for the project.
