As others have stated or implied, "It depends."
I would not do something like 'a 2015 1st plus unloading GW's contract'.
I'd prefer something like 'an unprotected 2015 1st from a probable lottery team PLUS a decent young talent prospect. The latter could be either a top existing rookie or sophomore or simply a pick from lower but still near the top in this year's draft.
I have to admit, I am very much more interested in Jahlil Okafor, who is the player currently likely to be #1 next year, than most of the players in this draft. So I'm not entirely dismissive of the idea of getting an extra shot at him in next year's draft. And there are a couple of other potentially great big men coming out next year as well.
But a shot in the lottery is only that, and to give up taking Wiggins outright would require a lot of mitigation around that gamble.
Absent of any specifics, for now, I'd say, "No."
