I'm not creaming my pants at that Boba Fett trailer but yeah it could work. For such a supposedly cool and iconic character, he was quickly turned into a punchline in Return... and utterly trivialised by the whole clone shit in Attack... All they need to do is make him a Lee Van Cleef type in Space Western stories with as little strings as possible to the mainline protagonists. Hardest bit is doing that without him talking (or talking much, I don't expect they will make make the effort of him being mute).
