Can PouchDB sync with MySQL / my current non CouchDB database?

No, the data model of your application has a lot of impact on its ability to sync, relational data with the existence of transactions make this harder. It may be possible given some tradeoffs but right now we are focussing on making PouchDB <-> (PouchDB / CouchDB) sync as reliable and easy to use as possible.
