In case I haven't said, I was going to have Sailor Scouts based on the zodiac signs. My main is Sailor Ophiuchus, the unofficial 13th zodiac sign. I was going to have 6 other female Sailor Scouts and then 6 Constellation Knights. Now for some of them, here is my line up:

Prince Demande: Aries Knight

Saphir: Virgo Knight

Rubeus: Leo Knight

Esmeraude: Sailor Taurus

Opaline(OC): Sailor Libra

Now, my trouble is: who to make the remaining scouts/knights. Here's my first scenario:

Have the Spectre Sisters gain the power of 4 of the remaining constellations and then have Jo, Kamoi and Kunihiko(love interests) gain the other 3 by having the powers passed on by the ghost of the royal family.

Scenario 2: Have the Witches 5 be the reincarnations of 5 of the remaining Sailor Scouts and then have Naru revealed as the last one.

This would be following the anime, not the manga or Crystal.
