That doesn't seem like it would be possible, if you want all the convenient hooks in VM's for them to be able to integrate with and be usable from the host system.
The solution really does seem like implementing those same hooks in non-VM environments, but preventing their actual usage behind permissions. In a VM, the permissions could genuinely be granted or denied. In a non-VM they would always be denied. But malware could never be able to tell why it was denied permission.
