Fisker made some attractively styled EV's. Elon should hire their designers and put them to work asap on completely restyled Model 3's and Y's.
Yeah, I don't think Fisker and Musk are going to be working together (again) any time soon, based on their first go round, and subsequent relationship.
One might argue that Fisker's concepts still live on in the S (which he designed for hire) and the 3 (same ole, but smaller).
Some time in the future, when all the principals are dead, and the NDAs don't matter to anyone any more, I hope someone spills all the beans on Musk and his dealings with Eberhard, Fisker, etc.
