G13 for new hope?

Hi,
I'm playing a rebels-team (CLS, Han, Chewy, R2, 3po).
On my shard I can hold Top50.
What do you think, who should be first G13?
Han? CLS? or maby a droid?
Chewies benefits are the worst so he will be last.
I'm working on a Padme-Team as well ... but there only GK is G12 ... and Padme only 5*

Maybe GG is a good choice, too - but my separatist droids are only G10-G11

Thanks for reading
