There are already suitable models in the games assets, look at the engineers bases (salene jene?) and those little little remote mining colonies you sometimes stumble upon on planets surfaces if derping about in an SRV. There is IMHO only one reason we cannot have such devices, especially the latter smaller ones, and that is the lack of persistence of the universe.
If you drop 2x units of cargo from your SRV, and mode switch, or hit supercruise then return to the coordinates where you deployed the cargo, its gone. We would need an element of persistence to the universe where if you drop said cargo, log out and go to work, its still there when you log in in the evening otherwise your MB4 mining machine mogul career would require you to be handcuffed to those assets praying the server doesnt disconnect you.
I'd be interested in prospecting planets, then buying mineral rights to resource rich zones and hauling deploying and servicing (taking supplies to maintain, and extracted resources from) my mining rigs. Even better yet, let me add modules to that settlement, turrets and skimmer hangars to stop rouge SRV pilots shooting up and plundering my mining settlement, let me add Anti ship turrets to declare a no fly zone, let me really mean business and add a ship launched fighter hangar to launch Condors or GU-97's from to police the no fly zone, let me add a landing pad so I can dock one of my ships at.
Nearly all those assets are in game, bar the planetside SLF hangar, why can't we buy deploy and use them?
