I'd bump up the gravity to 1.075-ish, mash low, and use 10% sugar in the grainbill so it will superattenuate. Ferment around 68* to get the fruity esters from the yeast, and carbonate around 3 volumes. This would be similar to a Tripel, but with Kolsch yeast, sounds like the effect you are looking for... (why is everybody afraid of sugar?)
Because everyone's affraid of being accused of making hooch. If that's the case, the belgians have it down to an art :cross:
