I am afraid I can't. I am using a library called pint[1] in my project. It allows me to choose how its objects are formated but it uses format() internally. It adds some custom extensions to format strings which, as far as I can tell, mekes it hard if not impossible to patch it to locale.format_string(). But this is rather an excuse. I thnik, had this problem some time ago and I got away with locale.format_string() then, but honestly I think format()/string.format/__format__ shuld support locale aware "f" just like there is "n" that behaves like "g".
