This sounds great, but only if it requires human intervention to implement the block. I used to work in a NOC, and we would have loved to throw up a warning on the big screens that an attack is 80% likely from the following netblocks in the next N hours. That way we would have a strategy developed for defending before it even started and would be able to minimize downtime.
On the other hand, if you make this automatic you're going to piss off a lot of people very quickly because it's going to be wrong more often than you want.
