Trade Gillie and Dalton for DJ+ Brees?

Hey Guys! Should I trade for DJ? I would send Gillie and Dalton, and receive DJ and Brees. I have Bell, Howard, Cook, Abdullah and Gillie, and at QB I have Dalton and Luck. He is very weak at RB: DJ, CharWest, Blah Plaw, and Rex Burkhead. The only addition is, it is a 3 keeper leauge, and DJ will be going back to the pool next year, and Gillie is a 9th round pick. Thanks!
