I've gone over the first four scripts several times and edited them, mostly making minor changes to the wording of things. In a couple places. I've switched dialogue around between characters and added some new lines. I think the biggest changes are the following:
In Episode 1, I changed the reforging process so Fingolfin breaks Ringil into many smaller pieces before welding them together and reshaping his sword.
In Episode 2, I have Edhellos helping Aredhel and the other women with the grain. She won't be named, but it is a chance for her to appear on screen, and Diriel is there too. I might mention that in their conversations in Episode 8.
The more I think about it, the more I like Diriel being the besain of the Feanorian camp. This means that Caranthir's wife can't exist or can't be in Beleriand because, if she were there, she would be a female of higher status than Diriel. Maybe Caranthir's wife could be one of the Feanorians who drowns in Uinen's storm, and no one mentions her because it is a sensitive subject for Caranthir.
In Episode 3, my changes were mostly to the frame. I have Bilbo speak to the Hat Merchant and buy a hat from him. I also have Aredhel and Celegorm not taking Celeborn's warning about Nan Dungortheb seriously.
In Episode 4, I added references to Bilbo's new hat and named Annael's wife and son.
If anyone has more feedback or suggestions for the scripts, I can easily change them, and I am happy to do so.
