As others have said, financially it'd be very tough to do given KG's salary.
And why would either club do it?
While the T-Wolves might be vaguely interested from a PR standpoint, they certainly aren't going to give up any of their core.
And even if Danny is convinced that Doc can turn Beasley into the next Larry Bird, why would he trade KG for him now when he could just sign him this summer?
