Ya, I don't think there's any way to tell how much memory Big Blue or Pokefloats would take especially in comparison to other stages. I'm pretty sure Fountain of Dreams is just as taxing on the GCN as Mute City and Big Blue were.
Anyway, Big Blue's awesome if you play in Fixed Camera mode; the normal dynamic camera is what really ruins it. Pokefloats would be awesome if they added Pokemon or made a theme to it like you're fighting on blimps or hot air balloons of Team Rocket and the other antagonistic teams. Have some stuff like a houndoom balloon that breathes fire, a weezing balloon that pumps out smoke, or a sharpedo balloon that opens and closes its mouth.
