I doubt it. I would advise you to use a paper ticket anyway though; read on...
Oyster PAYG journeys time out after two hours, and after that you'll need someone to open the ticket barrier for you, which will waste time. Oyster season tickets don't seem to suffer from this problem, but the 1-9 weekly season ticket is about £65. Paper tickets don't time out.
Of course, you could plan your journey so that you exit and re-enter the tube network every two hours, but I'd just pay the extra 50p and not have to worry about it
