I've transmitted PSK31 and SSTV simultaneously using HDSDR and my SDR HF radio. HDSDR will take audio from multiple sources and transmit it at the same time. Even with a conventional radio, it should be possible to send both PSK31 and voice audio simultaneously from the computer to the radio. One would just configure the radio as if it were using any other digital mode and then use the computer mic to talk instead of the radio mic.
The PSK does not need to send any characters to be detected, so I just leave on a PSK carrier from FLDIGI. I'm not sure how well the detection would work with SSB on top of it though. I could try it.
