Well there's no debate over the answer to the first part of that question. Yes, other things CAN be done to ANH after Adywan. In fact, Adywan himself is revisiting it again. And a quick browse of the posts in this thread will bring up many ideas that Adywan didn't execute, or things people didn't like or thought should have been different in some way.

As for the second part, who is going to do it, well, that's not so easily answered. I am incredibly busy with paid work to give too much time to my own edit at the moment, but I for one am definitely working on it. And other people surely would like to be doing it but don't have the resources and/or time. But the will is surely there, and while that remains, then ideas for what can be done will continue.
