No, Palpatine would want people to fear the Jedi, not feel sad like they're some misbehaving celebrities. Subtly turning their public image towards faceless, warmongering religious fanatics much better suits the "they attempted a coup and melted my face off" narrative. When Order 66 goes off, he wants people to be terrified to open their doors to any Jedi stragglers. He wants them eager, desperate even to inform on them. He certainly doesn't want anyone questioning the official narrative with "but they looked so heroic in the holo-reels!"
