You never should modify files by yourself in /usr (except /usr/local); doing so will make your system unreliable (and as seen here break it in some cases). Using alternatives is not possible: you'll break all those modules and extensions that are available for one python version only.
If you do want to set another default for your own use, use /usr/local/bin, or ~/bin.
