I noticed one mention of master Ropal early in part 2 (2:48).
Part 2 works nicely, it’s a lot of package but it doesn’t drag. Much like part 2 the pacing is intense and makes for an entertaining duology. I honestly like master Ropal because his death scene is surprisingly dark, but I agree cutting him (and by extension, the second MacGuffin) makes for a more streamlined story.
If I were you I’d keep Lightsaber Lost, and place it after the Bane arc as originally planned (or maybe before Seven Warriors to fit Ahsoka having more maturity and initiative in that episode). LL is filler, sure, but works for me to give the sense Ahsoka is taking time away from the battlefronts, references her relationship with Jocasta and foreshadows both a) Ahsoka becoming more mature and b) teaching/guiding younglings.
Regarding the rest of your planned episode order I think its alright in a narrative sense. Personally I’d probably put the Return of Maul as the s2 “finale” and Maul piracy as a premiere of sorts for s3, much as the original arcs were. The only continuity “problem” that the Maul and pirates episode would cause by being placed so early is that Adi Gallia dies there but later appears in the background of many episodes where the Jedi council is involved (one could possibly pretend she’s her relative and lookalike Stass Allie but then again Yoda in the Voices arc unequivocaly remarks that she is dead).
