 You could replace the file input when the URL field is focused:
 
 $('#fu').replaceWith('input id=fu type=file /');
 
 where #fu is the file input.

Sounds like a good idea - i'll give it a try in the morning and let you know
if i have any luck

wierd that there doesnt seem any way of directly altering the file inputs
value... perhaps its a security thing...

Yes, it is a security thing. Otherwise malicious developers would be
adding paths to user's existing files and be able to silently upload
user's files without their knowledge.
