Markers cannot href each other. So you'll have to simply duplicate a
marker when applying style to its user path (only if the hrefcount of
the marker is > 1, otherwise it's not needed). However the copied
marker should carry some extrension attr indicating that it's a styled
copy of another marker, for purposes of showing in the list only the
markers which differ by contents, not style.

I think it's possible to redraw all the basic markers (arrows,
squares, etc) so that they look the same but only use stroke, no fill.
This will simplify things a lot, as you'll just copy the new path
style to marker and that will paint it the needed color. More
elaborate markers will use fill too, in which case their fill color
will be determined by that of the user path. Note that per SVG spec,
unset stroke is invisible (unlike unset fill which is black), so in
the original markers you will need to provide stroke:black on
<marker>, and replace it with whatever is the user path's new style.
