She... could theoretically get her coworkers to test serums for her. Which might even be morally justifiable, if she's the only real person in the building, which: from the conversations she's had, she's increasingly more sure of. She doesn't know what any of these things she's making do, and many of them might end up actually dangerous, friendly simulation world or not. But on the other hand: doing that feels icky, and wrong. And it's not like she knows how she became self-aware, or if the other sims around her are incapable of going through the same thing. It would be genuinely fucked up to have experimented on someone before they became a proper person, like - well, like taking advantage of children. Plus, they're also genuinely very charming. Kind of stupid, but, you know, in a cute, endearing way. She could theoretically see the shape of the person they might grow into, if they got hit with the personhood ray gun.
So, in summary: no using her coworkers as test subjects, though it did occur to her.
She does head over to the item creation station and see about trying to create a ray gun that could maybe person people. Look, it's just as crazy as everything else she does here, so why not?
