Impossible to know without seeing an example - if you want to upload an
example we can have a quick look:
Please upload the files in a single compressed tarfile to
http://www.fmrib.ox.ac.uk/cgi-bin/upload.cgi
and then email me the upload ID.

Sure - you could use some combination of downsampling, editing and then
re-upsampling (using flirt) or else maybe the morphology options in
avwmaths to fill in between slices.
