We're currently looking into this, and if they are implemented for the Cutlass, it would just for the rear-ramp of the ship, not on the side-doors. It'd also be featured on all models of the Cutlass, so it wouldn't be something you'd need to worry about trying to melt/swap to a specific hull or model to have available for use.

Other note with this, outside of something like the Prowler where it has designed power surplus just for the Atmo-Shields, running them is going to be a serious power-drain to the ship. You won't be going full guns-blazing while keeping the rear-ramp open indefinitely and having your main external shields running/charging at full strength.

Last note, the current plan is that opening the side-doors will fully vent the rear section of the ship, for all 3 versions. You'll get some more rapid boarding/disembark when you're landed somewhere with atmosphere, but in space, you'll need to be fully suited up before opening the doors. Also, the toilet in the Cutlass is in the back section near the right side-doors, seat-belt not included.

Few quick things regarding those images:

1. There's only 1 set of bunk-beds in the cabin, not 2. We had initially started exploring 2, but removed one to make room for more appropriate interior-kit options for the cockpit section.

2. The maneuvering thrusters people are trying to find aren't clear to see in any of the images or the turntable. They're near the back ramp section of the ship.

3. The main-engines are also the housing of the retro thrusters, and are the only source of +/- Y (front/back) thrust on the ship. All the other maneuvering thrusters will be handling the +/- X (side to side) and Z (up/down) translations.
