Unfortunately no, but you can easily write a script which will do the
same. Here is an example, quick and dirty, but doing a part of the job
of -i:

#!/usr/bin/python

import shutil
import sys
import re

file = sys.argv[1]
backup = file + '.bak'
pattern = re.compile (sys.argv[2])
replacement = sys.argv[3]

shutil.copyfile (file, backup)
backup_h = open (backup, "r")
file_h = open (file, "w")
line = backup_h.readline()

while line:
    line = pattern.sub (replacement, line)
    file_h.write (line)
    line = backup_h.read()
    
file_h.close ()
backup_h.close ()
