For the Gauge-Theorists: Setup if I want to play him with Nahida(C2)?

Please correct me if I'm wrong here:

From my understanding I have two options that both work.

1. Apply more Hydro than Dendro so I have an Hydro-Aura Kyryll can LC with.
2. Apply more Electro than Dendro so I have an Electro-Aura Aino can LC with.

I'm primarily interested how much more I need:

• Is an infused Anemo Burst enough to make to work?
• Do I need the big ones (Fischl / XQ) or do other applicants work as well?
