It's the proverbial rock-and-a-hard-place dilemma. Stick to the contract and the original description: lose the funds. Fork and change how ethereum works and you've proven conclusively to all participants that a power grab is possible and that the contracts are all subject to future novel interpretation.
It sure seems that way, but this doesn't have anything to do with breach of contract per your original comment. Forking and changing how it works seems completely kosher from the contractual side, but seems like a bad idea for the reasons you stated.
DAO -> DOA either way.
