Your Honey malt and your Aromatic malt are basically the same, I would replace both with Weyermann Dark Wheat Malt which is of the 5-7L color range, this would would get your whole wheat taste IMO.
And then due to Wheat, you would no longer need flaked oats for the body.
I would then simply fold this flaked oats percentage into Chevallier percentile giving more of the bready malt your looking for.
Your crystal/caramel in the 8.5% of the malt bill range should carry the sweetness and the Weyermann Dark Wheat is also somewhat sweet.
Simplify.
There, now I feel lots smarter now.
