The propmasters working on TROS assumed after TLJ when the saber broke that Rey would build her own saber (I dunno if JJ pushed to keep the old one)

“I don’t think JJ ever seriously considered a double-bladed saber for good Rey, I think he thought it would just be too evocative

of Darth Maul, especially for a general audience, that it’s something a dark sider would have, not a Jedi.”

Leia’s saber has elements of Obi-Wan’s, also the grip has the same design elements as Ben Solo’s, may have been inspired by his mother’s lightsaber when building his own

While Filoni was an important voice in early development meetings for the ST, influence was limited as he was too busy with his own projects to delve into the ST & live action stuff until Mando

As expanded on in Bloodline, the scandal over Leia’s father Vader being revealed to

the public and ruining her career was a Michael Arndt idea

The fish nuns assassins on Kijimi concept may have come from JJ or Terrio

JJ didn’t screen films for cast and crew like Rian did pre-TLJ as he was in such a massive time crunch for TRoS (as far as Phil was aware)
