help me with a trade WHIR

[jojok12]

ok so heres my team

qb- cam newton, big ben
rb- adrian peterson, peyton hillis, frank gore, willis mcgahee, brandon jacobs, thomas jones
wr- mike williams (TB), brandon marshall, mike thomas

i only start two wide recievers and my flex spot i start a running back so i start 3 rb's.

im thinking of trading frank gore and peyton hillis for a big name back like mcfadden or lesean mccoy.
what do you think of this trade? or should i look at trading some other way?
