R2 Rework

R2 synergy with C3PO and other Astro Mechs. 

R2 Synergy with light side Jedi and ships (repair, possible raid synergy for unlocking doors--maybe a Grievous/Count Dooko Raid that reflects the beginning sequences of Revenge of The Sith on Grievous' ship?) 

Just some ideas, but overall, lmk what yall think of an R2 rework in general to synergize with C3PO specifically.
