Likely not unless they make it 3 inches in:
> "The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 9 cm2 (3 centimetres by 3 centimetres) and lies on the roof of the nasal cavity about 7 cm above and behind the nostrils."
