Root 5.1.1 - Dont care about tripping KNOX

I'm on the newest OTA of 5.1.1, and I want to root and don't really care about KNOX anymore. I just want to do so without wiping my phone or losing any data; custom ROMs are out of the question.
PignPong and Chainfire don't work for 5.1.1, the non-KNOX tripping solution breaks vital features, so I'm wondering if there is another way.
