You're not going to be able to do that. That's a system level restriction that you can't get around.
There are ways to create working hard links, but that would only work file to file, not directory to directory.
You can create symlinks pretty much anywhere else in /data but /sdcard (in all of its forms) won't work. You could create the symlinks in /data/media/0 but, although an entry for them would appear under sdcard, it would be inaccessible. The only way to successfully access those symlinks would be via /data/media/0
The reasons for this (in extremely simplified terms) is that /sdcard is emulating a fat32 file system, even though the underlying system is ext4 or f2fs (depending on device/ROM). fat32 doesn't support symlinks.
