We know from Maxwell equations that light can be seen as an electromagnetic wave.The oscillations of vectors E and B are into directions perpendicular to the direction of wave propagation. Can it be (theoretically) conceivable to have light as 'longitudinal wave' in which vectors E and B oscillate parallel to the direction of motion?

The short answer is no.

For any EM field, the direction of energy flow, defined through the Poynting vector is always perpendicular to the electric and magnetic fields at any point.
