As long as he gets he may have to rebuild the audience practically from zero.
The current audience likely want it mostly as-is. Not many are guaranteed to want to shift to a whole new medium.
Even those that are willing are mostly going to want to see the story progress. Currently fans will mainly rejoin when the current cliffhanger resolves. Oh, they'll dip in to see how the rewrite goes but they won't want to retread old ground.
It would almost be better to just start over with a whole new story. People who like the narrative style will still get something familiar but with no preconceptions or regrets about how the story should go.
Then, once established, revisit Evermore after having proved that he can complete a project before revisiting an abandoned one.
Because, yes, to all intents and purposes Evermore is abandoned, even if the narrative isn't dropped forever.
