I think so, yes. A plugin has access to the playback, it can pump data which
has been prepared (see the metronome, chip8 or video plugin) or synthesized
on-the-fly (less feasible).

One way:
If the bitrate of this audio signal can be matched to mpeg frames, in a way
that a small integer amount of bits fall within a frame (384 samples for
layer 1, 1152 samples for layer 2+3), you could prepare frames for all the
combinations if it fits in the mp3 buffer and play them in an order defined
by the binary data.

Another way:
Generate mpeg-data on the fly and pump that, but you'd need a very
quick(-and-dirty?) kind of encoder.

A third way:
attach a little microcontroller to the remote pin (for physical
interfacing), and pretend to be the floppy rather than the datasette. A
counterpart plugin could maybe emulate the disk drive, accessing disk
images.
