Level 5 oneshot Bard/Rogue/Cleric help

A while ago our group did a level 5 one shot where everyone was required to have at least 1 level in Rogue, since the game was about a heist. My friend played a Rogue 2/Twilight Cleric 3 half elf, however in practice was basically a bard without bardic inspiration. Our DM is doing more one shots and we've all decided that we'll keep running with this group of characters for now, however my friend who was the cleric wants to tweak her character a bit by actually adding Bard levels. Her current thought process was 1 rogue, 1 twilight cleric, and 3 bard, but she can't decide on her subclass, and she also worries about her stat allocation. Whats her best move? According to her Twilight Cleric is irreplaceable, ties too heavily into her character's backstory
