What you propose is equivalent to trying to do cryptanalysis without any cipher text or other material.
Equivalently, you could just take the small plaintext seed that you know, and nothing else, and run it through a probabilistic language model to predict the most likely message. (e.g., a Markov chain text generator)
The key point here is that, all things being equal, access to the OTP-encrypted cipher text gives you no new information (beyond perhaps an upper bound on message length).
