We would be particularly interested in space craft internals for boarding action scenarios. We got the FW Realm of Battle Zone Mortalis boards which are great but do not have the level of modularity a DF set would have.
But what style would they go for? there are so many more than for a castle or dungeon.
So we think KS7 will have something along these lines
To requote Nate from KS6.66 Update #19:
"Good news - the Dreadportal indeed carried us out of the Nine Hells. However, we've found ourselves in a untamed stretch of forest filled with savage beasts, otherworldly plants, and a mysterious eldritch glow on the horizon. It may be months before we can bushwhack our way back to Valoria.
But rest assured, as soon as we return we will tell you tales of what we have discovered, out here in the Wildlands..."
