I'd love to see a Makoto in the 1/4th scale. I've been pretty hyped up since her being revealed as a playable character in Super Street Fighter 4.
What's so cool imo is since the last game she appeared in (Street Fighter 3: Third Strike), even though she uses the most vanilla of fighting styles, karate, she attacks with just an devastating, brutal power and energy. To see the character in action, check out this 3v3 team battle, where a lone Makoto player (J) is a team's last hope and wrecks the entire opposing team!

Style wise, I think she'd work well with the mixed media (e.g. in particular, her signature, the belt/scarf wrapped around her neck)
For cool poses, I really like the ending punch on this super (Ultra combo I in SSF4,

Also, the charging part of her special dash punch move, Hayate could work:
For a normal attack showing a very karate-look, this attack somewhere mid-animation could work well:
For EX colors, this one is pretty cool imo:
A probably cooler EX would be when her skin turns reddish when she goes into her "rage mode" ( Tanden Renki super,

I know this is a tall order, but I hope the SF inspiration of the people behind PCS stays strong and someday, we see a Makoto (PCS style rocks!
)

Pretty late, but I think this would be pretty cool look for Guile's EX: shades.

This probably won't happen (considering the teaser images out), but for M. Bison, the rare look of him with the hat taken off (but not gone) is pretty sweet. EX?
