I don't know about standardized builds: by the time most of our characters get to epic levels they tend to be pretty weird. The epic squirrel who took some specialized classes to be a familiar was kind of strange, and his pyromaniac mage friend who accidently merged with a star was worse. Still, if you want a bunch of level 10+ spells, as well as a straight build option for epic level characters (and a playable system for deities: we've had deity and non-deity characters in the same party and still had a balanced game), try the Eclipse link below. You can't lose anything looking at a shareware .PDF, and you might find something useful.
