That's 4-5 dice for a single turn, if you're lucky. Depending on green dice is always a bad idea. Always.
I've also never been a fan of running the YT in formation with smaller ships. Even Dutch + Lando isn't exactly a walk in the park, and they're both turreted.
Why would it be a single turn?
Because its green dice your gonna lose the stealth device if everyone is shooting you.
