In theory yes. In practice you're talking about a massive cryptographic break, to the extent that it's not worth worrying about if you're going to be using those random numbers for anything that involves real-world cryptography. If you can't trust your CSPRNG to be secure when your attacker gets ahold of 1024 bits of output then you can't trust anything you're going to do with the output of your random number generator anyway.
