Liquidsoap can definitely do what you want, feeding into Icecast.

You can set up feeds such that one has priority over another, such
that if the higher priority one is not present, the lower priority one
gets used, and do fancy things like smooth crossfades between sources.

I personally use that facility to provide a breakdown message if a
feed goes offline or it goes silent for more than 30 seconds.

Have a look at the recipes that are on the Liquidsoap site.

Liquidsoap will decode almost anything you can feed at it and output
in many formats simultaneously.  For 64kbps aac+ you will need the
Fraunhofer encoders (and their ocaml adapters).

No version of ices will do aac.
