Malcolm Brown and Robert Woods for Godwin or Amari Cooper?

League is full PPR. Owner with Godwin and Amari Cooper has Todd Gurley. Think I could/should turn Malcolm Brown and Robert Woods into one of them? Which would be better? Also, I would pick up Raheem Mostert off waivers with the open slot afterwards.

I have Thielen and Davante Adams starting at WR currently, so player I pick up would most likely go into my flex.

Thank you in advance!
