As I was browsing in the XoS thread...I would LOVE for HiX-Man or Percy to adult Jean up to Marvel Woman and leave the "Girl" behind.
That simple change could be a consequential moment for the character (quite similar to when she crashed into Jamaica bay as MG and emerged as Phoenix.)
Edit: Count me as one who also likes the XFF stylised X-uniforms (minus the straps around her hips and thigh). I would love to see an updated version of it in X-Force.)
