Hmm, following your criteria this is what I got so far.
Lacus Clyne from Gundam seed/Gundam Seed Destiny
Asuka Langley Soryu from Neon Genesis Evangelion
Kallen from Code Geass
Saber from Fate Stay Night
Atoli or Alkaid from .Hack//G.U.
Samus Aran from Metroid
Eleanor from Bioshock 2
Would you like more suggestions?
But going with Kagomekai said just go for it, and if you like the character then do it.
When in doubt, just take the next small step.
With that next step take a deep breath. It calms the mind.
When the mind is calm you realize the best is still yet to come.
