Yes, it is possible. The problem is that they could be tweaked a little bit and just need to be loosened and rotated or they could be bent. In either case, it is pretty easy to get the clip-ons loose. Here is the diagram showing the two bolts you will have to get to. The diagram is for an 05-06 zx6r but should be the same for you.
Also, since I cannot see your bike and don't know how bad the crash was, you might of bent a fork tube. But, I don't know. If it is just your clip-ons, you should have no problem finding some in the "for sale" section or on eBay. Good luck.
