Potential uniter trait for the successors of Alexander and Achaemenids?

[Atraphoenix]

I love Getai traits, then suddenly I thought is it possible to add the same system for Alexander's successors or Achaemenid Successors.
I think coding can be copied from Getai traits so there should be no problem to add to the trait files.

What do you think is it worth trying? Any idea?
