She couldn't have known it at the time, but the best course would have been if Nala Se had cooperated from the start. Then Hemlock would be stuck in a research project making small progress, and nobody would be out to capture Omega.
I'm fascinated by Omega's story on a meta level, because it seems they are working a connection between the first Legends (oh, how I hate calling them that...) trilogy, which gave us Thrawn and Mount Tantiss as a cloning facility for the Emperor, and the (in)famous "Somehow, Palpatine returned" in The Rise of Skywalker. If that's the case, I'm appreciating the attempt to retroactively make sense of a somewhat murky story line.
If Omega's blood is able to support a Midichlorian count transfer with no degradation, I guess theoretically they could make her Force Sensitive. Not sure how that would end up happening, but it should be theoretically possible. Project Necromancer I believe is in support of Palpatine working to create Force Sensitive clone bodies of himself he can transfer himself into. I guess its pretty hard though and they've never made a clone that could maintain the midichlorian levels transferred to it until Omega, which Nala Se knew, but her attachment to her was greater than her loyalty to scientific advancement. Not to mention the Empire destroyed her world and perhaps made her species all but extinct, so I don't think she's in any hurry to help them in the first place.
We first heard about Project Necromancer in season 3 episode 7 of The Mandalorian with Commandant Hux (father of General Hux in the Sequel Trilogy) in charge of it 🤔.
