I aint that good a programmer so this is just a synop from my limited experience. I managed to cobble my thingspeak code to pass 7 different values back from a single arduino. So so long as you have the module here set up to receive X pieces of data it should work.
I like your idea so if you come up with anything do post back.
Do unto others before they get chance to scr3w you over
