Lost DJ and Woodhead, stacked at WR, need trade advice

Full PPR. Lost DJ and Woodhead. Stacked at WR and want to trade for RB.
My team:
QB: Mariota, Alex Smith
RB: Riddick, Kamara, Doug Martin
WR: Diggs, Amari Cooper, Demaryius Thomas, Randall Cobb, Golladay, Beasles
TE: Witten, Jared Cook

Who can I get if I package 2 WRs? Which should I package and which RB should I go for?

I would package diggs and DT for freeman, Gordon, or Murray. Or I would go diggs and galloday for gurley/Howard. Howard owner might be afraid that cohen will eat into his touches

Thanks of rite advice man. Ended up trading Cobb and Jared Cook for Terrance West and Jimmy Graham. Think I made out alright
