Is Bossk Zeta leader a requirement?

I’m going to do Bossk lead with Boba, Dengar, Greedo and Bane. Is it enough?

Put a zeta on his leadership and you are golden

Yes.
It makes them much better.
But, in terms of the event,
you don’t need his zeta.

But, his zeta makes BHs very hard.

I have seen people with only g12 bossk and g10.5 others, zeta on leader, and they unlocked chewbacca 7s

I think you can do it np but I would strongly suggest dropping a zeta on him anyway. Its super useful in all areas of the game.
