ships float, because they displace water. I think you will be creating a floating house boat. However anything can be done almost if you put enough time,blood,sweat,tears,and most of all $$$$$.
pumps will work however you need to know your last 100 to 200 rain fall in a givin hour. Then figure out how much water will be displacing your basement so that you can install the proper pumping system, and amount of concrete to hold the house down from floating. Good idea to call on a professional engineering company in your area for your best advice.
good luck,
