This seems like a good idea now that I think about it some more. The Kickstarter goal should be the minimum amount needed to get a viable product to market. Once you've figure out that you can make it, you should shift your product to a store model and direct users from Kickstarter to the store to purchase it.
Too much money in these cases may create a sense of complacency and encourage "take it and run".
