Peff has a couple of animoog inspired Reason combis available on his Facebook page! Here's his description:
for those who don't have animoog for iPad, i've put together a combi in Reason 6 which demonstrates a 4x source fader on the modwheel which allows you to fade between four different graintable sources (Y Dimension of animoog). The index control rotary adjusts the grain index point on all four graintables (X dimension of animoog). Unlike the app this combi is only mono, but for the type of sound it generates, one voice is probably all that you need
"Like" Peff on Facebook and go to his "Reason and Record Media" section to download the combinators!
