go very easy on the cardamom if you use it. otherwise you'll be sampling it this time next year to see if its drinkable yet(about 3 months here). alot of times i will add 1-3 pounds of honey or 2 kinds of honey at flameout to belgian blonds. of course it serves as your simple sugar and dries the beer out but the honey leaves a great "sweet" flavor. i've countered that sweetness with a small amount of oak for a short time. the oak tannins can match well to that sweetness. of course if your adding alot of honey you'll want to add it after the yeast has consumed some of the less simple sugars although i've never had a beer stall from adding up to 50% at flameout. another thing i'll do is to pitch whatever belgian yeast that i'm gonna use for 5 gallons and use a 1 or 2 strain 100% brett pitch on the other 5 gallons.
