Verdict

Unsafe

Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Memory blackouts are likely

Risk / Physical + headspace

This combination carries bodily risk and can go badly psychologically. The headspace part often arrives first and makes the physical part harder to notice.
