honestly, unless they do a spin-off series (similar to Wonderland, a one-and-done arc) focusing on the UW, we're done with it. I doubt there will be any future need to go and rescue characters.

Now, if they do choose to do a spin-off of the UW, showing Arthur fighting Cruella for control, then they can choose whether or not to bring back the other characters from the River, and it might be interesting if they allowed it. James would obviously side with Cruella, and I feel that Gaston and Milah would side with Arthur. And Pan would be a wildcard, not siding with either side (similar to how Rumple tends to be in the above ground. Like father, like son).

But, as far as the main show is concerned, any characters in the UW (including the River) are lost except for use in flashbacks (and I don't see many flashbacks where these would be useful characters).
