I'd also drain the downspouts to the same place.
That was my original plan and is still my back up plan. The reason I redirected to an exterior solution was for a couple of reasons. First, since I have 5 separate compartments under the house, I would need to install this solution in each compartment. This would be expensive and the space is only about 36 inches tall. It would make digging the trenches and the holes for the pumps rather difficult. The second reason is because it was brought to my attention that the water could damage the bricks that make up the foundation. I figured that the best solution for the money, time, and the foundation was to stop the water before it had a chance to make it to the foundation walls.
All of this being said, your idea is still not off the table. One definite benefit to your solution is that if I ever have busted water pipe, the water would be purged from under the house before it had a chance to build up.
Thanks for the suggestion!
