Not only a good idea, it's a brilliant idea, at least for credibility of proof of work consensus mechanism. For a long time i've seen giant centralized pools as a biggest threat to bitcoin.
And centralization of them was undermining the whole idea of centralization, so i am glad that someone is rethinking how we should approach idea of pools.

Only potential problem i see in this is someone will find an exploit and steals one block of rewards. And that's something i can live with. Also as i am not an expert i don't know where the fud will come towards this but
i am prepared to read critique against this with a grain of salt.
