Hey, great!  I was thinking of doing it too, but it would take me
awhile to get to it.

The old code re-samples the signals pretty early in the pipeline, once
it figures out where each symbol is.  It should be possible to adapt the
old code to handle input at various rates, without much trouble.  That's
easier than resampling in the new code.
