It is theoretically possible to edit the databases (edit checkpoint 
file) and rearrange the repository. I have done this once. If you do it 
right the users will never notice since you modify the client view as well.
In the general case this is not possible but in the special case you 
describe it is.
And there are drawbacks:
* You have to spend some time researching the checkpoint file to 
understand how to modify the contents.
* You have to turn of p4 service during your "surgery".
* The potential for errors is, well, there. And unless you checkpoint 
file is small there is no way you can verify it 100%.

So, I would not recommend it. As I said I did this once and it worked 
like a charm but still I very much doubt that I would do it again. The 
circumstances where a bit special, the depot organization was a mess and 
really did make life complicated for the developers so..

I have heard that others have done it too, but I do not know any details.
