The original LEGO Ideas submission for the Pirates of Baracuda Bay was basically a completely new idea that wasn't made in LEGO before, but the finalized set ended up being 2 in 1. One of the builds is a shipwrecked island, similar to the original submission, and the other build is a revamp of the Black Seas Baracuda... one of the most iconic Pirates sets that fans of that theme have wanted a re-release for years.
So perhaps if Sokoda's Bionicle project gets approved, maybe we might also see some sort of 2 in 1 feature in the finalized set... Maybe a buildable Mata Nui Robot or something like that.
So who knows? We might get some sort of "Constraction" build with the finalized set if it gets approved.
