stone/brick patio in damp area and over septic fields

Hey all - I have an area of my backyard that seems to take the brunt of big rains. Thankfully, I have french drains installed in the area. But the lay of the land doesn't entirely direct the water to the drains, so I end up with some standing water. In the winter, this area doesn't get much sun, so it pretty much stays wet and sloppy longer term.

We've wanted to put in a brick-paver or big flat natural stone patio stones in this area anyway.

1. So long as I slope it away from the house and toward the drains, no problem?
2. It may cover a small section of the septic field. No problem? If anything, I'd think that would be helpful.

I was just curious what will happen to the ground under it. Even after 6 days of no rain, this area is still boggy from the last rain. So if it was completely covered with stone pavers of some sort dumping into the French drains, I presume it would remain a bit dryer underneath over the long term.
