Thanks everyone for the advice - this morning, I think I have settled on Apollo 13 Ale.
Using 4oz of Apollo hops (in addition to 4oz of Warrior), this contains 13 lbs. of fermentables. The beer is shooting for the moon, so to speak, in terms of ambition and lack of worrying about the consequences. Will it make it to the moon? Will this beer cause a systems failure and need to return to earth? Or will the beer best the failed mission and actually be flavorful, delicious, alcoholic, and relatively drinkable?
