No. Removing free trade is what ultimately KILLED Runescape. That and removing the 'wild' aspect of pvp.
Grand Exchange is exactly the way Availer put it, ruins the roleplaying aspect of the server. Grand Exchange is like buying things online. You sit at your little computer (bank), you go through and find the best deal halfway across the world, you purchase the item and it's shipped to you. You don't have to do anything.
The year on this server is 1304. It would completely ruin the roleplayin aspect if we let this form of 'technology' be incorporated.
Good idea, just bad for this server.
