Data series with individual Y-axis

Hi,
I’m prototyping an application with two visible data series and an individual Y-axis for each data series. See the enclosed image.
The Stroke color of each data series, the TickTextBrush and the BorderBrush of the y-axis are updated by normal data Binding through the MVVM pattern.
The problem is that I am not able to data bind the Stroke property of the MajorTickLineStyle for the individual Y-axis.
Do You know if there is a workaround for this through data binding?
The project is enclosed.
