Trade Kittle and Chark to get Lockett?

I want a more reliable WR and would like to get Lockett by giving away Kittle and Chark.
I already also own Waller, who I believe can produce very solid points.
My WRs are Woods, Boyd, Godwin, and Chark.
Should I offer this trade, or should I try to get more in return? He has Howard for TE.
