Here's a freaky idea:

Build a "tube echo" with a large length of flexible plastic pipe, which has
been rolled into a coil. Connect one end to a small box which contains a
speaker. At several points along the pipe, drill a small hole and insert an
electret microphone into the hole. Connect preamps (probably with some EQ)
to each microphone. Then use your scanning circuitry to sweep back and
forth among the various microphone signals. In other words, do the whole
delay line with sound instead of an electrical transmission line simulation.

How's that for an unusual vibrato-chorus design?

One thing's for certain, it's sure to have an "analog" character to it.
