Trade for WR2? Upgrade at TE?

Format: 1/2 PPR - 2rb 2wr 2flex
here is my roster (excl. QB/K/DST):

RB:
Mixon
Drake
Chris Thompson
Dion Lewis
Ingram
Jones

WR:
Obj
Baldwin
Cole
Enunwa
Godwin
Shepard
Brown

TE:
Burton

Since I have a good amount of fringe RB 1/2’s along with FLEX WR’s I was hoping to trade for a WR2. Which players can I package and which one should I target?

For TE - is there anyone I can pair with Burton for kelce/Ertz/gronk?
