Clone War Chewie + K2SO?

Some time ago I read a post that CW Chewie lead (+50 defense and Defense up) and K2 taunting with her Zeta to gain stacking protection up was like, insane if modded right... (I’m thinking a defense team in G) however the missing piece I can’t remember is how to restore lost protection.... Jyn can, but she has to be lead, so that takes out Chewie..... anyone have an idea how to heal up K2’s protection? Thanks.
