it's quite possible, since the stencil is usually only needed when
trying to achieve a specific effect and even then readback is often not
required - for performance reason most people will usually try quite
hard to leave the data on the GPU only ;)

sorry, I've lost a bit track of this and what parts you got working in
the meantime. What is the problem you are currently stuck on? The
readback of the combined depth/stencil buffer or something before that
(like setting up the FBO with the buffers you need) ?
Cheers,
Carsten
