Instead of focusing on AHA styles, why not try to make variants?
Suppose you like American style IPA, and brewed a batch using
Chinook for bittering and flavor, and Cascade for dry hopping.
So you could try an English style, using say Northdown for
bittering, EK Goldings for flavor and dry hopping. Or Northdown,
Northern Brewer and EK Goldings. Or you could invent a new
style, call it "Continental IPA" and bitter with Perle, flavor
with Hallertauer, and dry hop with Saaz. That's the kind of
thing I like to do.
