Here comes the X-20A Brokk, also known as the Clown Transformer Face.
Named after the famous dwarf from the Norse mythology who, with his brother Eitri, forged the most famous personal weapons of the gods.

Originally built as a multirole super light spacecraft, the X-20A finally became a craft mostly dedicated to ultra-light/light payloads. But, if the cargo bay can be loaded with small satellites it also can be loaded with a one ton Mk1 cabin to carry some tourists. The front nose section could also be quickly replaced by the original Shielded Docking Port (but at the prejudice of the aesthetic) and it will become a true crew transfer craft once again.

About the propulsion, the first stage consists in two Kickback S.R.B which should be able to kick the craft to a speed of 1200 m/s, at an altitude of 40 km (following a 45 degrees climb) before shutting down.
The second stage for its part is propelled by a single Swivel, ensuring enough thrust to place the apogee around 400 km before it runs out of fuel.
Then Brokk will ensure the rest of the mission, circularizing by itself while the stages are falling down to Kerbin to limit the number of orbital debris. With more than 2 km/s of impulsion available after the circularization it still got enough possibilities for multi-missions.

About the return to Kerbin, the X-20A is extremely light once out of fuel and can be a bit difficult to keep at the right angle in the densest levels of the atmosphere. If some fuel is still available I advise to transfert every units to the front Mk2 tank.
For the landing, Brokk was not conceived as a craft able to land while gliding, it’s therefore not equipped of any landing gears. Instead three parachutes are present to ensure a landing around 6.5 m/s with half fuel remaining and less than 6 m/s when empty.

Finally, to be an economic reusable spacecraft, the X-20A ensure a funds return of about 50% if you are landing in the K.S.C perimeter.

The craft is coming with a 0.9 tons comsat having more than 4 km/s of impulsion available.

A stock rocket called Sleg X-20A Brokk. Built with 70 of the finest parts, its root part is mk2SpacePlaneAdapter.

Built in the VAB in KSP version 1.3.0.
