No. We already decided not to do that, because file naming conventions

You can do this toay with a pre-commit hook.

Again, no properties. This logic belongs in a pre-commit hook.

As I said, this is not acceptable behaviour for the client.

Now that's tricky. You probably won't even be able to create such a
working copy on Windows.

It does that.

Apart from the fact that your specific solution violates our hands-off
policy -- but a lot could be done in a pre-commit hook -- the key
remaining question is:
How?
Like I said, you can't have a case-insensitive comparison that will work
everywhere, because it's locale-dependent. At the very least, that means
you can't do the comparison on the server.
And before anyone starts talking about how "other version control
systems do this", well, ClearCase for one does not handle case
collisions at all, and you have to jump through all kinds of hoops to
fix them.
