I used my normal squads for the top 4, and then added strongest girls with enough Slice to get a red ship.

The boarders didn't get past my first squad on the first three missions, but I haven't tried the fourth as my ship was nearly destroyed in the third mission by the boss (though not enough total power amongst my 40 gals).

Also not tried mission 4 as trying to do both this week's event and the last days of the reissued Holly but behind in both as I put all my stamina last week into the Ampy drive (so some of the stamina usually meant for the new event was spent catching up on Holly).

Will be tight to get both Holly and another 36,000 or so tokens by Thursday and Tuesday respectively without spending a Gem to top up stamina.
