Whether it's reasonable depends on the size of the payload. For example, if a 12 kg single-stage rocket has 11 kg of propellant inside it, 6000 m/s dV would require a specific impulse of 246 s. That's attainable, about on par with the Space Shuttle solid rocket boosters, though obviously miniaturizing one of those into a man-portable system would be difficult. Same with fitting the launcher hardware and the guidance system capable of hitting a literal fucking satellite from the ground into one kilogram.
