Bitcointalk is one thing, where people are aware of the subtleties of the background to this case. Major investors who have never heard of "smart contracts" up till now will not touch it with a bargepole once they learn that immutability can be compromised in this way - whether by mining consensus or in any other strategy. Your job as a miner is to consolidate history, not rewrite it.
Further, instead of confining the loss to DAO investors where it belongs, you will now be imposing it upon the entire Ethereum holder community.
