gave this a go 
indeed, you can use touch size or position to feed IN on rings… so the theory works.
however, the output on Gliss is very clean, so you don’t get the same effect as a contact mic.
… where the impurities, provide the ‘texture’.
so what I did, is instead
plaits → vca (in) → rings (in)
gliss → vca (cv)
this was where the run really starts… basically you can then use touch size or touch position to then open the vca - and important, gliss is responsive enough to make this feel very direct.
different signals from plaits (noise, oscillators etc) give very different fx.
of course, the next step, is chuck this into beads, and you open up a very large soundscape,
that begs to be played with… altering plaits/rings settings create some really dramatic results.
what nice, is not doing things this way, your not only getting a strike, but your also able to continuous sounds, depending on if you tap.
(you can also strum rings with gliss… but I preferred the above)
I then tried replacing Rings with Elements… this felt even better, not sure why, perhaps just how I had it setup!?
there is another possibility I didn’t try… there is a scale/offset mode.
using this mode, I think we could remove the vca , so do plaits → gliss (in) → rings (in)
anyway, back the EMM, as thats what this topic is about 
you could obviously do the same trick plaits → gliss (in)-> emm (in)
however, probably what I would do is send the gliss signal into the audio in. (so its audio rate)
then multiply the audio in by a signal source e.g. noise, then going into a biqbank
… obviously take a LOT of care with levels, as this can easily blow your ears/speakers 
but I think it’ll be very ‘organic’
