As an aside, today all the downstate Illinois districts you drew would be Safe R except the 21st. It is impressive how quickly this area has changed sides.
Even that would be likely R, since it looks pretty similar to the real IL-12. And honestly, I think Republicans would have held some of these suburban seats in real life 2008. Kirk or Bob could have won in the 9th, Roskam in the 10th, Biggert in the 11th, probably more in the 12th, 13th (Kinzinger?) and 14th. Not to mention Schock in the 17th, Johnson in the 18th, Shimkus in the 19th, and obviously a Republican (maybe Rodney?) in the 20th, with Bost flipping the 21st later.
