Hey guys - thanks for the suggestions - detailing continues:

Few things to note - There's no way it's going to feature 5 "wings". For one thing, there would be a serious potential IP issue, but it also doesn't make any sense imo - there would be no direct counter force on the other side of the craft if jets were unevenly spaced around the pod to help stabilize the thing as it screamed down to the ground.
The overall size I can play with - but everyone does currently fit - and the smaller the better for prices...
I hope to offer both closed and open options - I just have to figure out how I'm going to slice the thing up for casting. In any event, the doors wont be separate, rather there will be two "bottoms" - one with open doors, and one with closed.
Here's a bonus shot of the pod landing, viewed from below:

As you can see, the stabilizer jets "flower' out, helping to create drag like an airplane wing, while the jets on the ends level it out. The engine on top actually fires downward, acting as a drag chute without the drag chute. I want to make it clear how this thing might be able to slow down enough to safely deliver it's cargo, rather than slamming into the ground, turning its occupants into pink jelly.
I may also provide an "in-flight" option like this if there is a demand.
