I think it'll depend on the hopes they had for the line. I'm guessing they were thinking relatively small ES anyway, since this is niche artistic concepts based over the famous cannon counterparts. I'd be surprised if they don't throw out a Starkiller as well, but it's possible they weren't planning on diving much deeper into the line outside of these initial pieces anyway.
While these are somewhat unique conceptual counterparts from the early days that somewhat reflect the final film characters, I'm not sure a bearded Han Solo and not so Wookie-looking Chewbacca would do as well!
I will buy the **** out of those bearded solos if they make em.
