Freshwater Flush Tank

It appears that we will soon be designated a "no discharge" zone, including galley waste. I'm thinking that I will have three through hull fittings that will almost never be used and probably never have to be used. So I am thinking that I should remove them (Head outlet, galley sink outlet and lavatory outlet) and glass over the holes. If I add a freshwater flush tank I could then remove four through hulls. So my questions are:
How to size the flush water tank. What percent of the holding tank should the flush tank be?
Should I use galley and lavatory waste as flush water. That way the flush tank could serve as holding tank for the sinks.
Is there any danger associated with glassing over old through hull openings? Assuming competent work.

Re: Freshwater Flush Tank

If you have good seacocks on them maybe you can just close them and leave things as they are in case you want to sell your boat at some time.
