Help with team building?

I love the cowboy, but i already have both Firefly and Rappa using the super break team ;-; (HMC, Ruan Mei and Gallagher/Aventurine)

Considering these are the supports i have (+Pela and Welt), which other teams you guys think i can make. My Bronya is buildless since i got Sparkle and Sunday and i'm willing to rebuild her, but a team without her would be great :,)
