You might try extending the logic for computing the
logfile size in mkntfs_initialize_rl_logfile() from
mkntfs.c.

This is just byte pairs giving the upper-case code
for each character : for example at index 'a' (or 0x61*2)
you get 'A' (pair 0x41, 0x00).
You might try setting UPCASE_LEN to a smaller value in
unistr.c.
Of course you may have to deal with unwanted consequences.
