Besides having no idea what you're trying to say, I don't think you're considering the problem.
Here's the same issue, solved with regards lines and their strokes distorting:
scale a line, not it's outline/stroke...
That's a particularly cool trick.
But I don't see anything similarly possible with Paint Brush based "strokes".
Please, consider that this is what I'm "painting" the line with, so I'd like the circles (dots) to not distort into ovals when scaling the path in only one dimension, see my answer at bottom:
