Should I trade St.Brown 1:2?

12 team 1PPR redraft league, need WR help and considering trying to turn St.Brown into 2 good WR, or a very good and decent WR.

Current team: QB - Mahomes RB - Cook, Monty, Judkins, Pollard WR - St.Brown, Waddle, Shaheed, Franklin, Ayo TE - Waller, Goedert

Currently 5-0 so I have some wiggle room, do you think St.Brown 1:2 is the move and if so what kind of players should I target?
