the Leake deal seems like a reasonable precedent, and Mella's decent but he's never been a top-100 prospect, so i'd think that would be do-able unless of course Hill pitches at this high of a level for 2 more months, then you're looking more for a Cueto-type package i'd think If the intent is truly to make him a reliever, I'd pay a slight premium to acquire him early. That way they can get him in the organization and manage his workload the way they'd like to, rather than watch him throw 6-8 inning outings every 5th day as the A's showcase him to the rest of the league. I'm worried about him running out of gas at some point with a starter workload, so the sooner the Cubs can get him pitching on their preferred schedule, the better.
