Can you have too much slope on a toilet drain line?

No. If you think about it, upstairs toilets actually drain through the walls and down under the foundation and footings, so you would have a 100% slope there. You can have too little slope, but never too much, since gravity is actually what drains a toilet. Yes you can. Pipes that run vertical are not a problem because friction is not acting on either the solid or the liquid matter. Where a pipe is sloping steeply the water can run away leaving solid matter behind.
