Trade away Kamara?

So I am setting happy in first place in my 8man home league with this crazy team:

QB: L. Jackson, C. Wentz
RB: D. Cook, A. Kamara, C. Carson, M. Mack
WR: T. Hill, K. Kupp, C. Godwin, K. Golladay, M. Evans, T. Willaims and T. McLaurin
TE: Kelce
DST: Pats

But I am a little worried about Kamara with Brees being out and the fact that D. Cook is an injury-prone player. Do I send an offer to the Barkley owner that would include A. Kamara and someone like K. Golladay or M. Evans for Barkley? I can afford the hit at WR but a hit at RB could send me home crying. Would you consider sending D. Cook instead or will he continue to be a top 3 RB ROS
