Would something like this work?
Carlton trade: Bryce Gibbs, troy menzel and pick 21
Carlton receive:: kerridge, tomilson, plowman, Sumner, lamb, Phillips. 2016 first round pick via Adelaide.
Adelaide trade: Sam kerridge, pick 13, pick 28 and next year 1st round pick
Adelaide receive: Bryce gibbs and troy menzel
GWS trade: tomilson, plowman, sumner, lamb and phillips.
GWS receive: pick 13, 21 and 28
No chance. Adelaide would not give up 2 first round and 2 second round picks for menzel and gibbs.
