To answer your question about the post Sarlac Fett. None of the comic books had Boba in any diffrent armor then he was seen in the movies. More or less I think they assumed Boba had multiple sets of armor, so the set ruined by the Sarlac would of been discarded. So blame lazy artist, but the only comic that had grown up Boba in anything besides his regular looking armor was Twin Engines of Destruction. And that just had Fett walking around in cloths all bandaged up.
So I guess the good news is you can go as wild as you want, just won't have an pre published references
