I think it's worth remembering that the concept of having Themed lands, in which every ride shares a common story, is still relatively new (outside of Disney).
When Nemesis first opened it shared Forbidden Valley with Thunder Looper, The Beast, and Beastie. None of which followed the same theme.
The Forbidden Valley of the early 2000s is the one most people remember. But even then The Blade and Ripsaw stylistically matched the post apocalyptic feel, but not in story. A giant cutting blade and saw are a perfect match for each other, but would have more in common with Thirteens 'Forest out of control' story than 'a monster from another world'.
X-Sector is similar. Before The Smiler Black Hole, Enterprise, and Submission were more generic space than specifically tied to Oblivion. What mattered is that they all shared a style; Black with a bold font, each having a unique colour to set them apart.
I'm sure this new ride will have a long and complicated story linking it to Nemesis, and maybe setting up future plans for Galactica. But I'd rather it be a good ride first, with a theme that feels at home in Forbidden Valley.
