Trade Saquon in a keeper league?

So I’m pretty desparate for RBs now that I lost Saquon (and Mostert for a few weeks). I’m in a 2QB, half PPR, 2 keeper league.

If I were to trade Saquon for another RB, what kind of return should I be hoping for?

Someone like J. Taylor or Josh Jacobs. Someone young with a ton of upside. I would say Kamara but probably not going to happen right now.
