R2D2 event question

Iceih_SWG

How many 5* characters do I need to unlock R2D2?
I will never get to 7* anytone, but I can get 4 characters to 5*, would it be enough?

If it's like the others you need a full 5 man team of 5* toons to unlock.

It's the same as the yoda/palp event, except it requires empire. To unlock R2 you need 5 empire characters at 5*.
