Few if any areas will allow the low heel elbow to be used as a closet bend. And since the tub will be 8′ away it will need its own vent. To be completely legal and insure proper operation, all the fixtures in the basement should have their own vents due to positive pressure forces when the upstairs plumbing is used.
