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
in The Mandalorian Armor, it says that Fett's helmet was the only piece of his armor that was still usable. it also specifies that he had at least one more set of armor in a weapons-and-supplies cache in some locked down cave on Tatooine that he used for his employment by Jabba the Hutt. how i do still like the idea. but i think your left ear should be silver because his ROTJ helmet ears are...
You guys realize that posh hasn't posted any new updates on this thread for a year and a half? It was a cool idea, and maybe someone may resurrect it and try it, but his last post was July, 2007
