Of course you may!
Ren/Joker: Magician
Morgana: Chariot
Yusuke: Lovers
Haru: Emperor
Futaba: Priestess
Sumire: Hermit
Goro: Empress
Makoto: Justice
Ryuji: Faith

And Ann is the protagonist, of course! Everyone is introduced according to their arcanas as well, meaning that Haru in the au will be introduced when Yusuke is in canon and so forth. Thanks for the ask!
