What about something along these lines:

I'm making the assumption that this is a precursor to New Orleans making a deal with LA, or another suitor for AD, meaning dumping Hill has some value to them. It's not a first for Mirotic, but they get a good player with a flexible contract in Favors, and get off Hill's contract. I think that's about the best value Mirotic will pull right now.
Memphis gets their two firsts, which it seems is their main priority in dealing Conley. Most of the incoming salary is expiring.
Utah has seemed hesitant to give up more than a single first for Conley, but I guess I'm kind of imagining this as them considering it 1.5 first rounders for Conley, .5 of a first for Mirotic.
I'm on record as not actually being too into Mirotic -- and I still think he's super overrated around here -- but I could see this as a feasible approach to bringing in Conley and some additional firepower to recoup losses in outgoing value.
