Hi,
While doing your research have you looked into Nursing Advanced Practice Degrees? Years of schooling wise I am not sure it is too different depending how many classes you take...but there are Master's Degrees in Nursing that are advanced such as Clinical Nurse Specialist and Nurse Practitioner and work with doctors and do a lot of advanced procedures. As far as the med school goes, I am unfamiliar with the chances of getting in with a nursing degree...my only comment regarding that is that nursing school is a lot of work not to have a career in it...
Good Luck,
