Can Qi’ra teams mix it at the top of Arena?

Shadowscream

Specifically the team several videos on YouTube show:
zQi’ra, zNest, zHan, zzChewie, zL3-37

I’ve not seen it being used in the “wild”....

Killbot5000

Not that lineup. The same one that works in territory wars can crack the top 50 in a good shard.
Qi'ra, nest, zaalbar, l3, vandor

No.

Scoundrels cannot beat Traya or revan. Bastila maybe but that is behind us.
