For that, you need to have dynamic world like invadable planets, destroyable stations etc. Or RP like we did in Order with small outcomes / faster implementations in order to make it work. Otherwise, it is rather hard to do it, if not impossible.
This is not Ultima Online or Eve, the dynamics of the core game is too much different, it needs constant dev attention and agreement on all ends to carry on a RP (order one for example)
