RSV pilots are starting to get used more. There is definitely some activity now after a year or so of stagnation.
As for the ATW commute, it ain't easy. I also grew up there and get back at least every couple of months. I like it there and could easily imagine living there if not for the commute. But the 50-seaters on the United routes are very often full and if you are on the jumpseat there is a ballast problem. Skyway out of ATW is on the often weight-restricted Dornier jet. Same problem with the SAAB 340 of Mesaba. I have been bumped off of both of these airplanes because of weight issues. Many simply drive to MKE and commute to PHL or CLT on us.
ORD-PHL or ORD-DCA are pretty easy commutes.
ATW-PHL or ATW-DCA are not easy, but doable and if things go well actually not bad via ORD. But it can be dicey.
