Yes it would work but I would advise against using wire/iron or anything that a buck could get his rack rack hung up in. If the rack isn't ready to be shed, you could cause serious damage to a buck as he tries to fight his way free should he get hung up in it. A better method would be to leave them alone and let them shed out on their own, then do some tromping to find them.

If you've got to mess around, you could use 3 small hay bales. Lay two of the bales length ways, parrallel to each other and have 6 inches of space inbetween the two bales. Pour your feed in the center of your space then lay the third bale on top.

You could also pour your feed in bushes or where the trees are really thick. Trees should only be an inch or two in diameter so the buck can't get hung up and still could bull his way through the tree patch. They would have to work at getting the feed and shed an antler if it is ready to be shed.

Both of these examples would be much safer for a buck then using wire, iron stakes or rods.
