Just throwing a few ideas out there, in no way are these finished products. I just looked down the Fett page on Wookiepedia and grabbed some neat pics.
Fett in a lightsabre battle with Darth Vader in Star Wars Tales 11.
Fett in Dark Empire.
Fett in 15BBY.
Fett on the cover of Bloodlines.
Fett...well the source was better than the av.
Fett fist-fighting with Vader in a volcano...I have no idea where it fits into continuity. To my knowledge, Fett only ever fought Vader on Tatooine.
Fett, taken from a pic of him with Dengar during the Bounty Hunter Wars.
