I bought a little bunny/The Seven Substitute Shinobi

[Logan Darklighter]

Hrm... that'd be interesting for Katsu... suddenly going from Mist to Leaf nin. Not to mention, you'd have a lot of knowledge - shinobi wise - beyond that of a genin, and at the very least, emotional maturity. And, even if TGNH!Neshan doesn't know what's going on, he knows what basically happens to Team 7. As soon as he figures out whose roles he's playing, he'll have a considerable edge up. It'd be fun to see though -- but going with your previous explanation, sending three people to a dimension - even if each isn't a Hell!Sakura sorta deal - would rather unbalance... so it'd be interesting to see what you three's albatross turns out to be. =P
