Yeah, if you're going to run those different pieces, I would DEFINITELY play Dodona instead. Right now, that is the only thing that is holding San back at all, is that you're still forced to activate only one piece.
Of course, with 2 new Disruptive pieces in Han and Kyle, it shouldn't be too hard to play dirty tricks with your opponent and move San into the Disruptive bubble at the end of a round.
On switching out pieces from the current San builds....I'm just not sure. Last year I played around with the build where you swap out Boba BH for Boba Enforcer, Lando DS, and extra Ugos, but I just never felt like it had enough punch. Plus, the difference between Boba Enforcer's +15 single attack, and Boba BH's +18 Twin is actually quite huge. And to be completely honest with you guys, I never used Lando DS a single time during the Championships at GenCon. See if you can figure that one out.
Aurra JH is still going to be more valuable than Deliah and Lando or any combination like that as well, IMO. She can dish out 80-120 damage with Blaster Barrage. Her high Defense makes her a MUCH better choice than most other pieces alone. The other problem with subbing in Deliah and Lando DS is that you actually LOSE overal activations. So, in a match against my squad in the first post, you're going to lose a good majority of the time, especially when my Aurra/Boba Combo can kill one of your pieces every round once the engagement starts, but it will take at least two rounds for you to kill either of mine, possibly more if you don't roll well enough (at best, Deliah still needs a 9, and Lando needs a 12 to hit Boba in cover, and it's 10 and 13 respectively to hit Aurra!).
