looks like a simple SMaSH recipe (http://www.mrbeer.com/product-exec/product_id/12/nm/Cowboy_Golden_Lager) so you can add whatever you like to change the flavor profile.
some suggestions, feel free to experiment, don't do all of these at once, or do all of these at once
-Change the yeast; maybe a kolsh yeast.
-Add a little maltose to up the body
-add some fermentatables to up the ABV; maybe honey or maple syrup
-zest some oranges; add to fermenter
-add some fruit; think strawberry blonde
-add more hops; kit is prehopped but you can add more to change the flavor depending on how long you boil them.
