Shame about the rules
I was going to suggest naming them after the pilots of the Angels in Captain Scarlet:
Rhapsody, Harmony, Melody, Symphony and Destiny.
Yes, I know that Destiny doesn't really fit with the others, but I guess Gerry and Sylvia also had problems trying to get a group of five names to fit into some contrived rules-based namespace.
Biting the hand that feeds IT
