It is true, that for obvious reasons (like characters already existing in the game) some GLs are the wrong version or are not really what I would consider a GL.
Disclaimer: This is just my personal, humble opinion and should be taken as only that. Others will have different views on this matter, which are just as legitimate. ?
Also as info beforehand: I am not a big Fan of the sequels.
SLKR - The right version but I am not sure about him actually being worthy to be considered a GL power/reputation wise.
SEE - The wrong version, I would have prefered the Episodes IV-VI version, definitely a GL lore wise.
Rey - The right version, definitely a GL lore wise because she is -all- the Jedi (lol), I just don't like the Mary Sue aspect at all so I don't really care about the character.
Kenobi - I am a bit torn about the version. On one hand this version is the one that is a great fighter and leader, on the other hand old Ben is the wise master. Definitely is a GL lore wise.
JML - Wrong version, JKL would be my preference (his first appearance in The Mandalorian and how his skills and fighting are portrayed there). Definitely a GL lore wise.
Vader - Absolutely the wrong version! It should have been Darth Vader. Definitely is a GL lore wise.
Jabba - The right version but I would not consider him a GL. Yes he was a well known syndicate boss but there were others just as known/powerful.
Leia - The wrong version. The princess we meet in Episode IV would be my favourite or maybe the later Jedi version at least (considering the Princess is already in the game). Definitely a GL lore wise.
Edit for clarification
