Picky stellarswirl team advice

I have been cursed with an affliction that makes me dislike nearly all anemo characters. Leaks are even worse, I dont even like the future Stellarswirl related character. The "good news" is that I can already build my stellarswirl team with what little I have.

The only 3 characters that survived the curse are Lynette(C3), Faruzan(C2) and Sayu(C6). I already have Sandrone and probably plan on pulling for Odette (and get Lynette C6).

I can always play Lynette off field but I was wondering if I could on field her with C6, would the dps loss compared to Sandrone too much? Could I play both of them quickswap? I like the idea of playing them together for lore reason. In that case would Faruzan be a "good" option? If not, should I consider using Sayu instead?
