Let the Cavs have Love, particularly if they have to trade Wiggins now to do it. It's better this way than they getting Love next year via free-agency without having to give up any significant asset in order to do so.
And honestly, if we keep Sullinger around, we match-up well against the Cavs, and I think in a match-up between the two, I'll bet on Sullinger getting the best of him most of the time.
