The game needs a lot more variety of maps, as stated by you before that means a lot more work.
To this end, I think you should host the Goldhawk version of the Unreal map competition. Set out the rules, Give say 4 weeks to complete. 1 entry per person.
All maps once submitted can be freely used by Goldhawk
Pick a tile set or range for the compo- to help fluff out the emptiest areas.
Set criteria, such as where you want the drop ships located etc, size.
How to upload the map and where to save it.
I would recommend having 2 thread. 1 st is the compo thread, second is the map submission thread where mods delete all non map posts to help yourself stay organised.
There can be 3 stages of rewards.
Top 5/10 maps are gifted 1 free copy of Xenonauts
Top 3 maps get a chosen name in the game.
Winner gets to put the chosen name to a portrait in the game.
You could do it as a kickstarter announcement as well to push more interest.
I know you like to have a certain look/aesthetic, however maps are an area where a range is often better than the vision. This is because one person can become very repetitive in their motions and 5 very different maps can end up feeling very similar.
