This was Schur’s answer:

The only problem we really faced, when we came up with the idea that Simone died on Earth and thus gave Shawn the idea to disrupt Michael’s experiment by using people the Four Cockroaches had personal issues with, was that…it meant Simone died tragically young on Earth. We decided to just make a passing reference to that and not explain it, because it would be, you know, sad. In our heads it was some freak accident, akin to Eleanor’s death but not as on the nose regarding the way she lived her life.

With Jeremy Bearimy the Earth timeline was made largely irrelevant anyway so I don’t think the Bad Place would have had to intervene directly to make her part of the experiment.
