Those little bitty cops are hard to work with aren't they. But you have what you have.
Is there any way you could add on a run on the side so you could put the pop door on the side instead of in the floor? It would not have to be much, just enough that they could get out and down to that area underneath and back up. Then put your nests in one end of the coop and two roosts on the other end spaced at 12" apart. Then just use the bottom of your coop on that end as the droppings board.
You could probably hang food and water underneath, even in Indiana winters if you block it off so the feed doesn't get wet from rain or snow blowing in. Not sure how you'd provide access.
