If you mean you're currently accepted to a DO for incoming 2003 and want to defer it and apply MD 2004, you could get a deferral for work or personal improvement or whatever from the DO school (do it very soon though), and then apply to MD schools now for 2004. Your original DO school would not have any way of knowing you spent your subsequent year applying to MD schools, and you could just cancel your deferment if you were accepted to an MD school.
