Need to improve at WR, trade advice?

Need trade advice. I am very strong at RB (Barkley, Gordon, Mixon, Kerryon, Sony) and weak at WR (JuJu, Cooks, Jones Jr, Sanders, Anthony Miller). Like to package a RB and WR to get a better WR. Ideas of what WRs Cooks + Kerryon would get? What Mixon + Cooks could get? Thanks!
