Can you still be a Norse Pagan/Heathen without being Reconstructionist?

Just do something like wicca or wicca itself since its actually got many different forms. Wicca attempts to emulate the old religions even though it came from like 1950 AD. Take the Norse Gods and Goddesses and then just work it into a modernized form making a neo-asatru neo-odinism neo-theodism hybrid thing.
