What you could try (at your own risk)in desperation is to make a concentrated solution of hop extract with (drinking)alcohol. You may be able to purchase a product called KleenExtract(on the web), a 200-proof alcohol, going for $80/gal in Manchester, NH, or try 151-proof Bacardi Rum instead.
You may have to filter the hop solids out, as they tend to cause a geyser when opening bottle.
Some advantages: you can prepare only what you need at the time; you can san'ze cap, open, add extract, as much as you want, recap; The oils in the extract improve the settling of the yeast. Try it.
