The more Sailor Senshin the better indeed!
We need to have two full sets of scouts (soldiers, yeah yeah) this year so they can have a sexy cosplay battle to the death!
Wheee! We've just about gotten you trained, Tom! I'm proud of you.
Senshi change with a 'henshin' and the way the Japanese like to shorten names, maybe a "Shenshin" can be short for a Sailor Moon transformation squence.
Also, in Pretty Guardian Sailor Moon, there was a Dark Mercury (she was really cool -- and the guys thought REALLY HOT at the same time. Heck, even I thought so and I like guys!). Maybe a whole set of Dark Senshi vs Light Senshi...
