It's a close trade. I'd give McCabe the slight edge over Seabrook since he's on the #1 PP and Seabrook is on the #2 PP for the Hawks. Both are pretty equal in terms of points and shots. Byfuglien is definitely more valuable than Chimera though as he plays on the top PP for the Hawks and Chimera doesn't get any PP time at all. Personally I'd stick with the Hawks you have. I think you slightly downgrade if you take McCabe and Chimera. GL whatever you decide
