Who are these guys? Are they friends? Partners? Siblings? Lovers? Thats the beauty of imagination.
I downloaded a greedo bust file for 3d printing, sized it down heavily and printed.
Dremeled and cut the hole for the neck.
Stuffed the inside and coated the outside with apoxie sculpt to toughen the structures.
Painted then repainted bodies.
BSed a pistol for the female

Hope you enjoy and that they bring inspiration.
And may the fourth be with you...always..
