I don't think it's possible (but only sure to about 98% :D).  My 
suggestion would be to 
a) (easiest) just create a separate upload page  
b) (little more complicated) create an upload page that doesn't save to 
server but rather just converts the file to base64 encoded string, the 
flex app listens for the "uploadCompleteData" - that data will be your 
file in base64 encoded string.  You can send that in a web service.  
For b - you can look at the Excel library 
(http://code.google.com/p/as3xls/) - more specifically - look at the 
php script which does this to load a local Excel file into the flex 
app.  It does upload the file to the server, but doesn't save it, just 
spits it back in a form usable by Flex.

Hope this helps at least a little, I know it's probably not exactly 
what you're looking for though...
