GCS hold our 2nd, but we do have GWS' 2nd this year. Though its getting quite late in the draft at that pointTBH i couldn't really tell you what the Freo needs are other than they generally need more quality in their big's forward of centre, Brennan Cox was pretty good and is young but other than that I think everybody would agree Cam McCathy hasn't fulfilled his 2015 potential he showed at the Giants! He's still only 23 so there is hope but that is fading. Taberner has had his moments but has been injured and is 26 next year.... So my guess is they would be keen to get one of the big forwards in the draft so might be more likely to keep their high end pick, if they get the Lions pick then all bets are off, they may be happy to unload one of the picks.
If the Lions pick comes in I wonder if your original hypothetical is slightly reversed would that be enticing for the Dockers so Dons 2018 2nd(Pick 30) & 2019 1st plus Colyer for Freo's 2018 1st, so in basic terms Freo get back into the 2nd round in 2018 plus get a 1st for next year probably in the range like you said 7-15 and get some cheap fries on the side in Colyer.
I think the deal for Neale could kick this off.
Bris 2018 1st for Neale
EFC 2019 1st & 2nd & Colyer for Freo's 2018 1st
EFC & Freo 2018 1st & GWS' 2018 2nd for Shiel, Setterfield and GWS' 2019 2nd keeps us above board.
Bris lose Pick 4 (gain Neale)
Freo lose Pick 5 & Neale (gain Pick 4, EFC 2019 1st and 2nd round picks, Colyer)
GWS lose Shiel, Setterfield, 2019 2nd (Gain Pick 5, 7, GWS 2018 2nd)
Essendon lose Pick 7, GWS 2018 2nd, EFC 2019 1st & 2nd (Gain Shiel, Setterfield, GWS 2019 2nd)
