There was no reason to "reboot" Neelix. He may not have been my favorite character, but he worked well in the series exactly the way he was. If the entire crew were filled with flawless supermen the show would get dull very fast.
Quark was not a flawless superman, but he was certainly a fun character to watch. Neelix just seems like someone who is a danger to himself and everyone else around him. It was often counter productive to have him on board. It seems like he was playing a role similar to Gilligan.
