Oh. Solo. I didn't get that part.
The key is mass and dampening. The mass is provided by the weight of the camera and whatever weight you add. The dampening is a combo of bungies (like springs in a car) and the operator (sort of taking the shock absorber role.) Sort of a poor-mans fixed steadicam rig. I don't see it working solo
I think your best option is maffer clamps and magic arms, and short focal length. The wider the angle of view, the less noticiable the bouncing and shaking will be. Play around to find a wide to shoot yourself wide angle that doesn't look too distorted.
I don't think two angles is a pipe dream. In fact, it's probably a good idea (The reason I bought my pair of PD100a cameras was so that I could have two angles in a shoulder carryable kit.)
