Erik, you can have as many y axes as you want, and you can coordinate the axis label and line color with the color of the series. But we don't currently have the ability to offset the axis lines from the chart, as in your picture. You can float the axes over the chart area or dock them on opposite sides to seperate out the axis line, but they dont currently allow for how you have it visualized above. You may be able to achieve the effect by styling the axis label panel though, and coloring its right border.

The legend displays the marker and line for each series, but you may not be able to get it to align with the axis lines like you have in the picture above.

Also, the chart uses gridlines in preference to tickmarks, currently.

I would suggest submitting a feature request for tickmarks and the ability to offset the axis lines from the chart, if these are important features to you.
