Conquest Store Character Shards List?

Hi everyone,

I was looking if there is a list of possible characters that appear in the Conquest Store. I know it refreshes but I am wondering if CG lists what characters are possible. 

I will need 5 Dark Side Rey shards after conquest and I have bought all in the conquest itself with tickets, the pass for the extras and I am at the second last crate, best I can achieve. Debating if I should wait for the store or spend crystals and grind some challenges that I can barely do. I'd prefer not to waste crystals on challenges that are 50/50 but that all depends on if she is even available in store. Of note I saw her once before conquest.

Thanks!
