Thanks to liar/krnlyng (depending on where you are) sfdroid is all his hard work.

EDIT: If you really want to try it send me a PM, but it will break things.

flash this in recovery on top of Sailfish (install SDL2 if you haven't already). Click on the empty icon space in Sailfish app drawer with the sfdroid label to run CM inside Sailfish. No need for the xposed framework, Internet pass through works without it. I say Internet pass through because it doesn't matter if you have a WiFi connection in Sailfish or mobile data, both work.

Remember this is by no means finished, and still alpha quality.
