Trade offer using Kupp or..?

So I know everyone has been targeting lev bell all season. But now that its been 4 weeks I was thinking of buying into him since he has only 6 weeks left.

My Roster:
RB: Gurley, Conner, McCoy, Collins, A. Jones
WR: Adams, Cooks, Shepard, Cooper, Goodwin, Lockett, and Kupp

I have been thinking after this game I should just play all my Rams players lol but realistically I feel like I could flip Kupp for an upgrade. If I trade away Kupp would my team take a hit? Or is there another player you guys think might be fair in a bell trade?
