personally... i think, and to maintain the funniness of family guy, as well as make any of this actually entertaining to look at, you can't make an obvious person into something just because they already look it... such as joe as oracle, or the giant chicken as hawkman... but making joe flash, and the giant chicken as metallo or hell lobo... now thats funny. Personally i think its more funny if they look like fatties at a comic convention, then looking as close to the real superhero
