Even if the router idea works successfully with Comcast which I doubt, you are in violation of the user agreement if you do so.
It would be like stealing cable service back when it was legal for the cable companies to charge you for each TV.
It works.

Not since the telecom laws that broke up AT&T were passed. Way back then, AT&T actually owned the equipment and premesis wiring, and they could tell you what you could and couldn't do, even in your own home. However, once the gubmint put an end to that, you're not breaking any laws by having an unlimited number of systems using a single link to the Internet. The simple fact is that they're selling bandwidth, and can't tell you what you can and can't do with the data once it moves out of their domain of authority.
Of course, if you voluntairly sign a TOS agreement that limits your ability to do this, then I suppose you could have legal problems. But it's doubtful that any provider would look to the law for redress, simply because it would be hard and expensibe to prove, as well as generating a huge amount of bad press.
