Trying to trade Fitzgerald and Powell, who should I target

14 team .5 ppr league, I have Powell and Fidzgerald I would like to package into a more consistent starter for the rest of the season. I am indifferent between WR or RB. Who is realistic to target? Is Keenan Allen getting enough for thoes ttwo? (I have already been turned down by McCoy and Fournett owner).
