Tycho, the stealth ship pilot does sort of look like the figure, but the figure is actually the phase II clone pilot (as seen in this image of Warthog's newer gear). "Cat and Mouse" is indeed chronologically the first episode in The Clone Wars series, at a time when clone pilots were normally the same as they appeared in AOTC, aside from specialty pilots like the stealth ship pilot. This figure is based on the appearance that doesn't happen until quite a while later. (Why they didn't just switch to the ROTS gear, I do not know.) If you're able to get one, you could indeed repaint it, but it would be too inaccurate for an official Hasbro release.
