As others have stated. Swapping your current body for a light weight body with your neck and components is a completely reversible, no harm no foul process, = a bass you will enjoy and feel much more comfortable playing. I'm a firm believer in playing what feels good and makes you happy to be playing it. So, if you have what you feel is The neck for you, but don't dig the body weight, then by all means make it player you want.
