Trade cook and woods for lamar and bell?

Full PPR league and I have barkley and carson as my other 2 RBs

Have josh allen at QB so need an upgrade

Can’t sell him on Carson for Lamar? Lamar, Cook, and Barkley looks tough!!!
If I am you, I am trying everything I can to keep Cook and Barkley on my roster while upgrading where ever possible in the meantime.
Are there no quality QB streamers on the wire?
