I don't think there's a way. Errors would need to be fixed while demuxing by dropping broken audio frames and video GOPs. Perhaps
xport would do this for you?
You could also try
mplayer -vo null -ao pcm:file=out.wav to decode and pipe audio to NeroAACEnc and then pipe video to x264 in another run with
mplayer -ao null -vo yuv4mpeg. If that doesn't work well enough, just use MEncoder as you did before.

I know x264 will obviously only work with video, but will it discard the audio if I pass a file/pipe of muxed video and audio, or will it error out?

If you use x264's libavformat or FFMS2 support to input a muxed file or stream, it will discard the audio. When using raw video inputs, there's no way to include audio at all.
