Have you considered replacing Samus with Miranda from Mass Effect? Both are from scifi franchises, have skin tight bodysuits and roughly the same sort of personality. Miranda could even work for the Phazon series which can be Cerberus experiments or something. Although, you already have a Mass Effect series going with Blue Star, I don't know if you would want a second one. Just some ideas.
I appreciate the suggestion, but no. Namus Naran (Not-Samus Not-Aran) will be an original character (with an original name).
