No. Full support of this feature would involve a lot more than just the filesystem, since applications that look at directories directly have to know about about the backup versions in order to use them. Individual applications can do a "poor man's" version of this (e.g., the Gnu 'ls' support for emacs-style backup filenames), but again it's limited by (or to) the applications that know about it.
