Trading for Mixon

I’m trying to trade for Mixon, the Mixon owner has no WRs (he drafted RB heavy and now only has Snead, Stills and Woods after losing Coleman).

I have Hilton, Bryant, Tyreek, Garçon as my WRs, my RBS are Freeman, Murray, Stewart, Kelley and Burkhead.

Is Garçon and Stewart for Mixon a good trade? Or am I giving up too much on an unproven guy, considering I’m light at RB with Murray and Kelleys injuries?
