If you can find enough people in your area you might try it. We used to do it with some things when I was working. Seems like someone always felt like they got shafted when they had to pay their part of the shipping charges. Just make sure that everyone is clear on everything right up front. If something gets backordered it can turn into a major nightmare. Make sure you decide whether shipping is divided equally or in accordance with whatever someone buys. If the shipping is by dollar amount then it should be divided by the # of dollars and each person pay accordingly. If it's by item then divided it that way. If it's by weight don't even mess with co-op buying because it creates a horrible mess.
