Odds are you will have to change a few things,

1. the output sampling is the first volume this may not give the
complete coverage you want

2. It may appear more blurry as both are resampled 1/2 way.

3. During the fitting an attempt is made to generate an "overlap mask"
and only calculate the registration for the "most similar" parts thus
ignoring faces and the likes. This may or may not be applicable to
your case.
