This is actually a good idea for immersiveness, just send those who succeed their check the details so that the rest of the party isn’t privy
I’ve passed notes as the DM before, it does as a bit of immersion but there’s a lot more over head as a DM
Definitely would do it again though but only for a like a horror themed game or when illusions are involved
Had a nice illusion room in a dungeon, where only one player was seeing the reality. I pre-prepared the notes, so no extra overhead in the session. That one player was also cursed with not being allowed to speak, but that info was also in the note, so the others didn’t know. He tried to warn the others using sharades, and they thought he was cursed with mind control and turned on him, until he could convince them otherwise. That was a really fun round.
