It is sort of possible by setting the TIG_DIFF_CMD environment variable to something appropriate, for example using (and I don't know if this will be formatted correctly):

export TIG_DIFF_CMD='git show -p --stat -C -M --pretty=format:commit%x20%H%d%nAuthor:%x20%an%x20<%ae>%x20%ai%nParent:%x20%P%nSubject:%x20%s%n%n%b %(commit)'

You need to avoid using space except for where it really separates arguments, which is why the obscure %x20 is used. ;)

Another solution would be to create a script, which just expects the commit SHA1 as its first argument and then do the formatting there and then use:

export TIG_DIFF_CMD="/my/script %(commit)"
