This is a PPAPI to NPAPI wrapper in rapid development, but it seems to be fairly stable now. I've only tested it in Firefox and Qupzilla. It's hardcoded to look for the /opt/google/chrome/PepperFlash/libpepflashplayer.so file installed by Chrome, but you can also use the pepperflashplugin-nonfree package in wheezy-backports to just install the file in /usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so, then create a symlink to that in the Chrome location.
These are MEPIS 12 packages, but should work in Wheezy: https://drive.google.com/file/d/0B1UMhs ... sp=sharing
