Is the ratio consistent? Or does it change frequently during the piece.
My only experience with canon's is with one of Brian Eno's tape pieces
using Pachelbel's Canon, where he feeds notes into a tape loop which can
be played back at slower than real time. So, in the spirit of tape
loops, and especially if the ratio is consistent, why not write your
incoming notes into a circular table, which gets played back at a
proportionate reduction of speed?

Sorry I don't have time to patch that idea up right now, but maybe it
will be enough of a shift from your current line of thinking on the
problem to get you moving in a new direction...

best,
