2-For-1 Trade Advice

I absolutely have to trade two of my RBs for a WR1 or 2 in my full PPR league. I have good RB depth, and I’ll be activating Danny Woodhead from IR. I am pretty weak at WR. I was thinking of packaging Jordan Howard with Duke Johnson to try to get the best possible receiver. What wide receivers do you think I could target with that offer? I’d be good trading any of my running backs, but it really does need to be 2-for-1 deal. I’m 4-6 and am in must-win territory. Below is my current team.

Jordan Howard
Kenyan Drake
Duke Johnson Jr.
Isaiah Crowell
Tevin Coleman
James White
Danny Woodhead
Mike Evans
Keenan Allen
Vernon Davis
Will Fuller V
Josh Doctson
Hunter Henry
Corey Davis
Kirk Cousins
