Beating Leia event with relic delta

As I'm sure many of you are already aware, the introduction of relic delta broke several legendary events where the game gives you a borrowed unit. Because the borrowed unit is at relic 0 and the enemy units are at relic 3-5 ish, delta makes it so these events are essentially impossible. Specifically the first tier of the GL Leia event, the last tier of the Starkiller and Aphra event, and probably some others that I haven't seen. I haven't found a way to beat the Aphra event and can't access the Starkiller event, but I finished the prerequisites for Leia yesterday, and figured out a way to beat the first tier despite relic delta.

Essentially you need to target Leia with the smoke screen so that R2 is stealthed too. This makes it so the stormtroopers will split their attacks between Leia and R2, meaning R2 stays alive long enough for you to win. Other than that just spam specials to get the burning out and give Leia the offense buffs. I have the zeta on R2 that shares stats with allies which probably helped too. I only did it once because of tickets, but it seemed like you could do it consistently. If other people want to try it and prove me wrong or right, please go ahead. I'm hoping they make a fix to this soon, but they seem swamped with a ton of other stuff going wrong, so I thought I'd help people where I could.
