Yes, you could do this. We have not implemented this in our prototype yet,
but it is in the spec (see "Note 7" in
https://dvcs.w3.org/hg/FXTF/raw-file/tip/custom/index.html#feCustom),
exactly what you are asking for:

<script id="warp" type="x-shader/x-vertex" >
<-- source code here -->
</script>

..
<style>
.shaded {
    filter: custom(url(#warp));
}



Cheers,
Vincent
