Random Champ Idea

I was thinking of a sister-champ to Sona and I though of a guy who uses drums. Some ideas for spells would be that he beats his drum faster and increases attack speed and movement speed around him. And also another one where he konks someone on the head and stuns them. Or one where he knocks someone back with a big beat. And his ult would just increase ad, ap, attack speed, hp and hp regen, and mana regen. Thoughts or expansions on this idea??

I kinda want to make him like pyke but more team oriented.
