For me I'd have to say a ruckman would be the priority. If we can get our hands on Kreuzer it would be effing awesome, but I'd be just as happy if we could nab Bellchambers. Big lad (about 200cm), good strong build, very strong overhead, pretty athletic and is also a good forward option (actually started out as a tall forward). But to get Bellchambers and Cotchin we would have to hope that one of them has a terrible season or trade someone valuable for another 1st rounder.
Morton I see as probably floating around the 2nd round
