Audio encoding time is miniscule, compared to video, and a few options
can speed it up further (eg. lame aq=9).

Quite the opposite.  In fact, mencoder is likely the only program you'll
ever come across that can handle such a task, while maintaining proper
A/V sync.  A pass through mencoder results in the audio and video
streams being exactly the same length, and so an arbitrary number
of audio and video streams can be seperated and re-multiplexed as
needed.  With just about any other encoder, the loss of time-stamps due
to demuxing would cause severe desync.
