On-the-fly changing of linkTemplate

Hi,
I would like to update the graph link template before exporting the graph as a JPG file.
I saw that using a transaction I can set a whole new linkTemplate to the diagram simply using this, do you agree?

myDiagram.startTransaction("update_template");
var oldTemplate = myDiagram.linkTemplate;
myDiagram.linkTemplate = $(go.Link, ...);
myDiagram.makeImage();
myDiagram.linkTemplate = oldTemplate;
myDiagram.commitTransaction("update_template");

But in my case, I need to change only one property of the template (i.e. the line width) and I do not know how to directly access the strokeWidth property of the "Link ==> Shape" structure and set it to a fixed value (i.e. one pixel).
This is my linkTemplate (getLinkColor(), getLinkWidth() and getLinkLabel() are not included for brevity):

myDiagram.linkTemplate = $(go.Link,
    { selectable: false },
    $(go.Shape,
        new go.Binding("stroke", "cabletype", getLinkColor),
        new go.Binding("strokeWidth", "cabletype", getLinkWidth)
    ),
    $(go.Panel, "Auto",
        $(go.TextBlock,
            {
                textAlign: "center",
                font: "13pt helvetica, arial, sans-serif",
                stroke: "black",
                margin: 4
            },
            new go.Binding("text", "", getLinkLabel)
        )
    )
);

Is it possible to do that?

Thanks,
Guido
