As far as ingredients go, it's sounds like you've got a winner. I've never attempted to brew an experimental small batch before, but the quantities sound like they may work. One thing I would be careful of is overpitching the yeast. Since you are essentially pitching a quantity of yeast that would normally be used to ferment 5 gallons, it may produce some off-flavors; making an otherwise great recipe not so great. As for the type of yeast, personally, I like the White Labs WLP300 yeast. I've used it several times, and it always produces a great banana-like aroma and flavor. If you ferment it down in the middle 60's F, it will give off more of a clove-like aroma and taste; in the low 70's - more banana. I'd say go for it and brew a full 5 gallon version of your recipe (with adjusted amounts of grain and hops respectively, of course). After all, when the beer turns out great, you'll have to wait at least another 2 weeks before you can brew a full batch (meanwhile, those 10 or so beers will go quick!). By the way, loving the Conchords reference! - "I'm the Hiphopapottamus, my lyrics are bottomless.........." - priceless...
