Honestly, that would undermine Luke’s arc and strip him of his personal motivation to fight the Empire.
It would be a fake-out death for both of them, but Luke wouldn’t know that. He’d still believe they were killed and would never get to reunite with them, so he’d still have his motivation for fighting the empire.
I think Rodney’s idea is a very fun ‘what if’ concept.
Apologies for the late response. I’m saying it’s more meaningful if they actually were dead, and that Luke acting on a lie would be less meaningful than what we got.
