Yes, this is an idea that I have explored in my Bogen web page
(http://home.att.net/~drt-3d/toys/bogen/) where I write:

Have you ever thought of putting a stereo camera on a slide bar?
Sounds silly, does’t it? After all, you have the stereo camera
so you don’t have to use a slide bar every time. But, consider
this: Take a Realist-format stereo camera (70mm lens separation)
and slide it 50mm to record two stereo pairs. You get to select
from any of the following combinations:

- 20mm hypostereo by selecting the two inner chips 
- 50mm mild hypostereo by selecting the left of the first and 
  right of the second 
- 70mm normal by selecting either of the two pairs 
- 120mm mild hyperstereo by selecting the two outer chips 

Clever, isn't it!

What do you mean by "difference in height"?  There is no
difference in height and, yes, you can use an RBT mount to mount
any of these combinations.
