There was a proposal to add multiple sprites and the ability to change
the sprite visual. I believe it is not that difficult code-wise, and
Niels have laid the groundwork for it already. It is just that not
much happened between 4.2 and 4.3 (our fault)...

It is not that much harder. The main problem (as I see it) is that it
makes scripts dependable upon the presence of resources. So we have to
provide the option of failing gracefully if a given asset (svg element
id or file) is not present. Another option could be to "bundle" the
non-default SVG with the scripts, if KTurtle detects that a
non-default one is being used.
For simplicity, I think we can add a set of sprites as you suggested
(hedgehog, robot, turtle, bird) to the default theme. And then let
people select a new one as well, with something like

settheme "myfile.svg"
