This wouldn't be about the vehicles, though. The appeal to so many is that it would be a fresh take on something we all love. You may be good, but many of us have gotten bored, burned out, and blasé toward their collections. I'm not suggesting Hasbro axe their (gradually scaling back) line which we all love; I only wish for a new, fresh take on figures of my very favorite characters!
If it's not your cup of tea, that's fine, but dont mind us having some fun.
I'm imagining a Vader with lit and unlit sabers, packed with a mouse droid (I'd save the interrogation droid for the Princess), and a few swappable heads:
-Helmeted
-unmasked (3 parts!)
-Dagobah Spirit blasted open to reveal Luke!
...and maybe swappable gloves and the ability to display his upper air over or under his capes.
I'd happily plunk down $20-$30 dollars for that guy!
