I mean, obviously it's a move you only do if you're really big on your chances to land some great pieces in free agency. I just don't see those names being available. I see most of the big ones (Butler, Leonard, M. Gasol) staying where they're at. It's feasible that Aldridge could give up on Portland or Love could want to be alpha dog again somewhere other than Cleveland, but even in those two cases I'd be kinda surprised.
There's a pretty steep drop to the next level of free agency though. Now you're dealing with guys like Dragic, Draymond Green (neither of whom I'd pay what they're likely to cost), Middleton, rolls of the dice like Lopez or Hibbert, etc.
If we could convince Aldridge to come here and then throw the kitchen sink at Sacramento for Cousins, then I'd do those moves in a heartbeat - and I'd package Wallace with a pick to make room for that to happen, sure. But how realistic is that really? It's a nice pipe dream, but IMO that's all it is.
