I don't think Subversion's locking mechanism is something that can be modified in the way you suggest (not without rewriting a lot of the Subversion source code). I also don't think you need a locking mechanism at all. Just don't lock anything. Let people work concurrently. Yes, sometimes you may need to resolve conflicts. Hopefully it won't be too difficult to do so. I suggest you just try this way of working and see what you think. I think there will be fewer conflicts than you anticipate.
