well, to be honest, for there's never enough blondes in a fighting game X'D the echo fighter idea doesn't sound bad. Also the big stages of DOA6 looks good but i would like to see more small spaces, like the training gym or a bar. Also, as there hasn't been any pure boxing fighter in DOA history she could do that. Or i dunno, box-fit or like ranma 1/2 kodachi tatekawi's Martial Arts Rhythmic Gymnastics
a rapist troll... well, talk about diversity in fighting games XD
but yeah a natural readhead would be welcome in SF (there are SF redhead color variants for some characters but they aren't canon, same w/ SFEX2's sharon)
but it would be a lie if i tell u the number of blondes in SF worries me; my favorite fighting game girls are almost all blondes... and grapplers, some of them XD (cammy, mika, tina, blue mary, etc.)
from SFV i think i'm just waiting for a new grappler or El Fuerte, as Haggar probably will never be in a SF game as playable character.
from DOA i'll happy if eventually phase 4, kasumi alpha and alpha 152 made it to the game. if there are things i never got tired of is more blonde girls, funny grapplers and kasumis XD
