The Luko suggestion, sorry to have mentioned it now, was purely throwing up the best young KPF who isn’t settled and would fit out needs. He is also an SA boy with a potential ‘go home’ factor. Certainly isn’t anything more to it than conjecture and a bit of fun.
In terms of what it takes to get such a player, think Tom Boyd to the Dogs. Exactly same situation, KPF at the end of his first year wanting to go home. Dogs threw 1 mill at year at him, post his initial draftee contract, and traded a top ten pick and Ryan Griffen, their captain. Griffen wanted to go to be fair.
History backs that trade every time. Would we do the Dixon trade again, every time. Good KPPs are worth much more than midfielders.
Also the go home only factor is certainly not born out. Have a look at the players running around at Gold Coast who were traded in. Neale, McCarthy at the Lions, McGovern at Carlton, Franklin to Sydney, Griffen to GWS, Aish to Collingwood, etc, etc.
