[Plugin: Speedy Smilies] Possible to add support for Child Themes?

Would it be possible to add support for child themes? What I mean by that is that Speedy Smilies currently creates a minified version of my stylesheet, which is good. Problem is that my stylesheet is basically empty, since it inherits most of its stuff from its parent.

Thinking it should be possible to for example substitute

@import url("../twentyten/style.css");

with the actual content of that file before the minifying happens.
