i think using corn sugar gives the beer a specific cider snap to it, hard to describe, but i can usually tell if somebody adds a pound of corn sugar or something into a beer. just has cider like qualities...i don't know.
anyway, rice syrup solids would offer the same thing and are used frequently with lagers.
or
honey. i would just use a pound of honey, if you add it after flame out, but before pitching temp, you may get some residual honey flavor (which i like) but if you don't want that, just toss it in for the last 10 minutes of the boil. the boiling will destroy the delicate flavors of the honey, but you will get an increased abv.
