Are you there for a head injury? Sorry - couldn't resist.
Flaked grains will not convert. You need malted grains for the enzymes to convert the carbohydrates into simple sugars. Not only that, you need enough base malt to supply all the enzymes necessary for conversion of raw or flaked grains. Belgian Wits are typically 50-50 base malt to raw/flaked wheat. I can't think of more raw grain in something than that.
Otherwise, you have a nice breakfast cereal.
Now, replacing some of the base malt with some flaked grains can do wonders for a beer.
