Here's to hoping you make the RPG Class mod work alongside Thorium, Spirit, Calamity, and both the Leveled and Unleveled mods.
Also, here's my suggestion:
"Piped Piper" - Thorium exclusive
General focus on Summon and Bard
Starts out with Forest Ocarina
Special Power - Allow summon damage give the same type of Audio Buff as your currently selected bard weapon for 20 seconds (30 second cooldown)
