Whoops, I meant unstructured grid in that first paragraph. There's a filter called "Merge blocks" or something like that which will get you an unstructured grid. Tetrahedralize will do it too.
Resampling shouldn't be too hard in Python. You can create a vtkStructuredPoints grid and then resample your dataset onto it using vtkProbeFilter. Resampling can be very slow (hours for a small unstructured grid), but volume renders on structured points are orders of magnitude faster than on unstructured grids.
