I could really see a deal involving the Thunder and Hawks:

OKC sends:

Perkins
Maynor
Cash
Draft pick

ATL sends:

Harris

This is a huge salary dump by OKC so they can sign Harden long term. Atlanta gets a big bruising center to let Smith move to SF and Horford to PF. The Hawks have Teague, Lou Will and Korver among others to play in the back court. Maynor could be their immediate backup PG. Hell Maynor doesn't even need to be in the deal really, but I figure the extra PG is a good move for ATL. Reggie Jackson can step into that role after this year when Harris expires.

As it pertains to us. I think we might be able to get in on the deal by throwing Hansborough in the mix to Atlanta. I think he would make sense for them as another backup big who could play with both Horford and Perkins effectively. I think the only thing we would want is the cap space and possibly the pick from OKC. The Hawks have a ton of expiring contracts and Hansborough can add to that if they don't feel like re-signing him or come cheap if they like him. A lot of UNC fans in the south.
