Hi Hassan,
you can do that using same template for all language also.
add a cssStylesheet webpart in master page and use below macro condition in webpart enable field.
{% LocalizationContext.CurrentCulture.CultureCode == "en-US" |(identity)GlobalAdministrator%}
in above macro en-US means your language code
in which language you want to apply this stylesheet.
and use stylesheet path like below -
/CMSPages/GetResource.ashx?stylesheetname=Dutch
Dutch is stylesheet code name
.
Hope it will help and also it will be light weight.
Thanks,
