Frontier definitely has the skill to do it, I just don't think it'll happen in ED. Looking at all the dev comments, it's gone from "definitely something we're planning for", to "it would be cool, but no guarantee no eta" to "stop asking about it".
It's never going to happen as a part of the main game, there is a very slim chance it'll appear as a cqc style "bolt on" where they shoehorn some separate game as a main menu option (who knows, maybe they'll turn a permit locked area into a mini planet coaster where pilots have a licence to build their own dinosaur filled base... I'm out on a limb here lol).
Space legs in ED ain't gonna happen though. Much as I love the game, I don't think they've left themselves much wiggle room for future development.
