The best way is probably to override the existing Sitecore.Shell.Framework.Commands.CopyTo command and implement your own QueryState logic, where you basically just test if context.Items[0] has more than two levels. Having a message appear might be tricky, so I'd suggest having the QueryState method return Disabled instead. You should probably avoid traversing the item tree when testing how many levels you got. Traversing the item tree can be very slow if there are many items. Do some Solr Query for this instead.

Once you have your own CopyTo command, patch the type attribute in <command name="item:copyto"> configuration with your own class.
