That's the idea, I think, yes.
Combined with posn-point which lets us find the XY coordinates of
a particular buffer position, it should be possible to build (in Elisp)
the right SVG image and tell Emacs to overlay it on top the text.
Ideally, the primitive could look like a `display' spec which says
"overlay the image at offset XY relative to the current position".
But if it's too difficult to handle it that way, a simpler (from the
C code PoV) approach might be a window property which says "overlay this
image over the whole window's text".
