The use of comma instead of dot depends on the collation in the locale,
e.g. 'de_DE.UTF-8' has it.
Re. a blank between the number value and the unit: why not use e.g. sed
to post-process?

  $ stat -c '%s %n' * \
      | LC_ALL=de_DE.UTF-8 numfmt --to=iec-i --suffix=B --format "%.2f" \
      | sed 's/\([0-9,]*\)\(.*B\)/\1 \2/'
  10,52 KiB a-ten-K-file
  4,00 KiB dir
  0,00 B empty

Is this what you wanted to achieve?

Have a nice day,
