If you're unsure about releasing them on Saga cards, then maybe you should tweak the sculpts a little. Give the Imperial Officer articulated knees and give the Rebel Trooper both type of elbow articulation points so it's arms aren't suck like they are and they both need working holsters.
Also you could include an accurate Mouse Droid with the Imperial Officer (the saber dart included with Dexter is around the same size, it is possible) and a console where the mouse droid can go into with a view screen on the console that looks like it's from the eye of mouse droid kinda like when you control the mouse droid in Jedi Knight 2. The articulated knees could make it to where he could sit on a chair at the console, kinda like the Chewie Dejarik champion. His arms are already posed to be perfect like that. Don't take away any articulation though.
As for the Rebel Trooper, you could give him a crate or console for him to duck behind/
That I think would make the Rebel Trooper and Imperial Officers worth being packaged on Saga Cards especially with the bigger bubbles.
