What other crisis paths are possible in the future?

We got Galatic Nemesis and Cosmogenesis, the xenophobe and materialist crisis, those are the easy ones to come up with. Galatic Nemesis is just the logical extreme of a xenophobe non pacifist empire. Cosmogenesis too seems like the logical exteme from a fanatical materialist empire, putting science in front of literally everything. So i was thinking, what other logical extemes can we achive with others possible crisis paths?

Maybe a pacifist/xenophile one, where you are trying to "freeze" the entire galaxy in place to prevent any more conflict and loss of life, maybe freezing in time or just shielding every world idk.

Or a megacorp one, where you try to suck every resource in the galaxy, leading to every other empire dying of "starvation" (dont ask me how that would work gameplay wise).

We could also have a gestalt unique one, where you try to achieve perfect unity with the entire galaxy by making everyone one with you. (Just a driven assimilator but with a big machine at the end)

Spiritualist is kinda galatic emesis, since it is heavily based on the shroud and maybe a shroud entity is manipulating your empire.
