“You can use ssrc-multiplexing by setting the SSRC of the RtxParameters in RtpEncodingParameters.  RtcpParameters is not the right place for this.

Session-multiplexing is not supported by ORTC.”

[BA] Overall, BUNDLE compatibility is the  important consideration here.  It would not make sense to put audio/video as well as RTP and RTCP on a single port, then have FEC on a separate port.   This is also why the Multi-Session Transmission (MST) transport mode of scalable video coding (see RFC 6190) is not supported.
