I assume you mean *re*defined, and yes, it can. Add a <script> element 
to the page with the function definition in it -- it works well to 
define the function in the userscript, then do something like

   elemScript.innerHtml = doSomething;

(Don't type elemScript.innerHtml = doSomething(); -- that won't work.) 
That will expand the function properly. (You may still want to put in 
the usual /*<![CDATA[*/.../*]]>*/ chunks to wrap the script, of course.)
