Some logos have some typical elements of their chuubas in their logo like Korone's or Mio's hairpin or Subaru's cap. We're also not bound to use a rectangular shape.
We would also need a pictogram. Most teams use their scaled logo but there are teams like /awat/ or /ag/ who use a completely different icon. Maybe that's a good test if the logo is distinguishable.
