No to fro.
Second torso I'm okay with the taunt or a thumbs up victory pose. No peace sign though lol.
Or a beat-up Ken readying a shoryuken. Trouble is he begins readying in a crouched position which won't work so it'd have to be the frame after he leaves the crouch but before the ki forms. It's a completely different leg stance though so probably won't ever look right.
Edit:
On second thoughts, given the position of the legs in his fight stance, the taunt is kind of the only option.
