Thinking about it, it's possible:
Make the audio files go to the compressor's side chain input directly
and to a delay. That delay's output goes to the speakers.
This way, the audio from AES will fade out before the files' sound gets
to the speakers.

Making the audio files fade in some time after the audio files have
ended can be achieved by a reverb with long tail before the
sideband-input of the compressor.

This way, you could solve your requirements with one
sideband-compressor, one delay, one reverb, a command-line-player for
your audio files (mplayer, mpv, ...) and a cron-job that triggers it.

Best regards,
