Physical beidou team

Basically I'm trying to build a beidou team where she is the main DPS. I'm planning to use Beidou, C6, with 2p bloodstained and 2p pale flame and prototype R5 Charlotte, 4p mililith(I don't have her yet and don't know which weapon I'm going to use) Mika, c0, 4p song of days past and favonius or the new event weapon Bennet c2 with noblesse and alley flash They don't have a lot of investinent yet, but right know I'm hitting 8k per attack with beidou, and more than 30k with the prototype passive! I know physical damage isn't meta and beidou isn't perfect for it, but does anyone know how to improve this physical team or the builds in using?
