Considering Dynamis can be used and influenced to recreate societies wholesale as shown in the Dead Ends / Omicron beast tribe quests, and considering that Hermes says that it's similar to aether, I don't think an arcane construct made from it would be impossible.
I also think you're way off kilter here, as you usually are, when it comes to the Ascian's capabilities. If Zenos with mothercrystal leftovers can mantle Shinryu and reach Ultima Thule entirely without a spaceship, then Unsundered Ascians should have little trouble managing something similar.
I think Yuella's idea about a Dynamis Primal is kind of weird, but I guess the idea would be it would achieve similar power to the Meteion hivemind, as all of their power comes from harnessing the majority universal constituent energy. It's more or less just a second kind of sentient entelechy but with a focus on positive emotion and stopping Meteion, kind of similar to how Hydaelyn was polar opposite to Zodiark and focused for the explicit purpose of Sundering Etheirys.
If they could make it, which they likely could given some time to have others study Dynamis, or by taking Hermes's knowledge of it by looking into his memories/soul with The Echo, then it'd work quite nicely.
As for your assertions before this point, you are getting away from the point of the thread in trying to justify Venat's actions within the story, where her rationale is only assumed to be correct by her, not verifiably correct, as her decisions were driven by her own fear rather than by logic. I don't think you need to bludgeon anyone into getting on board with your perception either. It doesn't serve the thread nor the discussion.
