Trade TY, Kerryon, Ridley for Kupp, Keenan Allen?

I’m 3-0, trying to sell high on TY, don’t have a ton of RB depth but this would really solidify some top WRs and I already have McCaffrey for RB. Is this a good move or is my thought process flawed?

Current WRs: TY, Ridley, McLaurin, Samuel, Kirk

RBs: McCaffrey, Kerryon, Montgomery, Sanders, Singletary and Breida
