TBH, I'm not really on board with the "scrap and redo" thought.
1) It'd be a massive amount of work, probably more than just fixing what's broken with Elite currently.
2) Obvious Time and cost savings areas (like reusing assets) would result in people being put off with paying for the "same game again".
3) FD's reputation would all but be ruined. Since they're' hardly one of the biggest dev studio's out there, their reputation has tangible value.
While I would love for Elite to either ditch solo and make a proper MP game (Guilds, factions, Player economy) or better yet (in my opinion) ditch the MP game and make a proper Solo game (Like Elite Frontier, or FFE), I can't see that happening.
My hope for the future of the game is that they just spend time adding depth to each of the "careers".
Exploration: for FD to add planet scanning and material collection like is detailed in the "year of concepts thread:
https://forums.frontier.co.uk/showt...op-concepts!?highlight=year+of+elite+concepts
Military: for these carriers to be almost mini-SP campaigns. Kind of like ranking up in the guilds in a TES game. Make it worth doing to, with rewards apart from credits. Things like unique ships, or unique modules.
Bounty Hunting: Dead or alive contracts. Having to scoop up an escape pod from a ship you've destroyed to collect the full bounty (why is this not already a thing?)
Smuggling: Made somehow different to just regular hauling.
