No. Jump into the 9th Layer of Hell.

Just run NG . It'll be smarter, as you can't access the Ultimate Persona and Secret Boss during NG anyway.

NG Plus. Apparently the plus sign does not exist.

I planned to, just wanted to go ahead and get them added to the compendium now instead of waiting till November to do the reaper trick so I'm high enough level

Trust me, I understand. I missed the opportunity with a few of them, now I have to do it the hard way on NG . While I'm glad the Reaper power level is a thing, I'm irritated it's all the way at the end of the game.

NG Plus. Muscle Memory will take time to remember the Plus Sign does not exist here.

REVIVE!
