Yes, it's simple, but the serial communication with the MAS is too slow
for 44kHz 16-bit playback.

The MOD format has the same problems as the WAV playback. But sure, it
might be possible to mix the MOD channel data with the SH1 and then send
the WAV data to the MAS.

See above.

In the MAS case, the problem will not necessarily be CPU power, but
rather (lack of) memory. The MAS has 4 or 8k of memory for both program
and data. For example, the Tremor OGG decoder has hundreds of kilobytes
of lookup tables.
