I remain unconvinced it would work properly, sorry. Definitely has potential in written form where you can change visual details and lines so easily.
Their hatred for Rey (who is just a child) would not be enough for them to want to die for themselves to ensure she suffers.
I’m sure Hal has more to say on the matter, but I feel this is one of those bad things that TROS does that simply cannot be changed without making things worse.
I never said they wanted themselves dead?
One of the key elements of this movie’s plot is that Ochi is using the same ship as her parents because he caught them and interrogated them. If that happened under the idea that they had abandoned her, they would have absolutely no qualms with giving up her location. Instead, we find out that her parents are dead and he stole their ship.
Now, I’m not sure if you could remove the death of her parents and create the impression that they’re still out there somewhere, but that still doesn’t really solve the issue with the ship. And the only reason they would still be alive is if they gave up her location.
