Sounds like a good idea to me. Finally, when someone says “that’s a hella-big number,” I’ll know exactly what they’re talking about. 
I don’t know whether it will go through or not, but it’s likely to get adopted colloquially regardless. It’s already pretty much there.
I’m still trying to figure out how big a “zillion” is.
Jeez, don’t they teach you kids anything these days? A zillion is the same size as a metric sh*tload! Everybody knows that!
