Dear Peter,
My initial reaction is no. While both spm96 and spm99 normalize to MNI space,
the estimation of normalization parameters is better in the newer version. If
you are looking for between group effects (you mentioned historical controls),
then systematic differences in spatial normalization could confound your
results.
Cheers.
Alex
