I have been trying to look for a BTC pool that would
- Allow you to mine
- Anonymously and without registration
- Reward you for a block that you'd mined up to x% (say 66% - 75%)
- Paid out the remainder of the mined block to the other miners on one of the usual share bases.
- Had very low fees - anywhere from 0% to 0.5%

I have not found a pool that fulfils these criterion.

So I was thinking that this might be an interesting opportunity.

Would you mine in a pool that offered these features?

Are there any other features / options etc. which would persuade you to shift from your current pool, or from solo-mining?

Just trying to gauge interest here. If I can drum up a threshold level of interest (say 1TH/s or so), I'd invest the resources needed to set this up.
