[pymvpa] Classify neural across two very similar fMRI studies?

Dear list,

I would like to apply pattern classification to a single seed region, in
which two fMRI studies revealed convergence. Each of these fMRI studies
used the same stimulus material across four tasks (to focus on top-down
effects by subtraction). Both these fMRI studies used the same four tasks,
but differed in the sensory modality on which the task is based (visual vs
auditory). In every other respect the fMRI settings/protocoll were
practically identical.
Here's now my question: Is it possible to train a classifier for neural
activity patterns in the converging seed region to test whether activity in
that area is sensory-independent or sensory-specific? Or is there too much
confound when comparing between two subjects from very similar yet
different fMRI studies? Any help would be greatly appreciated.
