There is a reason people brewers/vintners have been racking off the sediment for hundreds of years: because it makes a better final product. You are going to suck up and disturb the sediment every time you pull a pint. My guess is that you'll waste about a gallon and it will never be clear. If you cut the dip tube, you'll also waste a gallon (and a good dip tube). I'm not sure why you would go to all the trouble of brewing and then cut out an important 30 minute step right at the end. I'm curious now though, give it a shot and let us know.
