I was thinking similarly, except:


 * No Naturals.


 * Plasma Island: Poison, Shadow, Crystal, Plasma


 * Shadow Island: Shadow, Crystal, Plasma, Mech


 * Mech Island: Poison, Shadow, Crystal, Mech


 * Crystal Island: Poison, Crystal, Plasma, Mech


 * Poison Island: Poison, Shadow, Plasma, Mech


 * 3 Element and 4 Element Ethereals.

Songs:


 * Plasma: Weird, but major


 * Shadow: Old-fashioned, minor

Mech: Awesome fast rhythms, major notes

Crystal: Major, Happy

Poison: Minor pop
