BIAB split batch suggestion needed

I'd like to make a 10 gallon batch of kolsch doing BIAB. I'm going for a more bohemian pilsner type grain/hop bill. What I would really like to do is make a 5 gallon batch as-is and the other 5 gallon batch with some carafa II added to make a schwarzbier type beer.

Long story short, how can I go about splitting the batch and making one light and the other black while using only one pot?

1. Brew the first.
2. Rack to the fermentation vessel.
3. Clean your equipment.
4. Brew the second.
5. See step 2 and 3.

Not quite what I was looking for.





How about steeping the dark grains separate in a quart or of water,boiling then adding to one fermentor?

No worries. Maybe I should have been more specific about not wanting to do 2 mashes/boils.
