It would take more than a weekend for each figure. More like a week for each one at least, with a couple people working on it. Multiply that by how many figures there are that need updating and correcting, and you've got quite an expensive project, just for the hopes of community to support these revamped figures that may or may not carry much interest.

There are people who have made corrections to several figures, but due to eulas, etc, they can't be redistributed, so it winds up being a waste of time unless you're doing it strictly for personal use.
