Does she catch Luthen earlier?
-- Lonni warns Luthen but in the process burns himself at the ISB preventing Luthen from learning about the Death Star
--Luthen doesn't kill Lonni and secures his relocation.
-- Luthen either
(1) abandons the antique cover and presumably moves to Yavin effectively replacing Mon Mothma (see below).
Or
(2) accelerates assassination contract on Dedra where Coruscant where she is an easier target.
-- Syril is promoted to ISB. Feuds with Heert and is censured by Partagaz.

Life on Gorman
-- Gorman Front is not infiltrated, Empire opts for mass anti-Gorman propaganda but they did that in the first place.
-- Other strategies forced relocation or widespread genocide through a fabricated story, for example "asteroid collision".
-- with more confusion about the truth, Mon Mothma never makes her speech and remains on Coruscant until the Emperor dissolves the Senate.

Does Jedha survive?
--Rebels still learn about Galen Erso but Cassian is probably not inspired to defy orders and visit Kafrene.
-- Bohdi remains on Jedha. The Rebels on Yavin don't believe Saw Guerrera in the unlikely event he reaches to them.

Do the Rebel still eventually get the Death Star plans?
- maybe. Recall in Legends they acquired them through a completely different route.
-- after Alderaan is destroyed Rebels agree that best strategy is to disperse the Rebellion
-- Mon joins the rebellion much later.

Amaze amaze amaze

extremely clever use of existing parts (including all of Cassian's alter egos) but please calibrate your enthusiasm because he's left out Eedy Karn.
