The Steadicam sled treats the mounted weight as a mass to be balanced and does not distinguish between single or multiple cameras as long as left-to-right and front-to-back balance is maintained and the gimbal is positioned correctly.
Mounting a slide plate perpendicular to the sled base (standard camera orientation) is preferable to parallel alignment because it keeps the rig operable at the operator's side and maintains reasonable monitor visibility.
The physical shape of the weight on top of the Steadicam does not affect stabilization performance provided balance and gimbal placement are correct.

This is a conceptual discussion without documented testing of stereo rigs on Steadicams.
No specific weights, camera models, or sled configurations are detailed.
The response addresses balance principles but does not cover potential gimbal tuning adjustments that might be needed for a wider payload.
