I get off duty at 0700 on the 5th and plan on leaving as soon as I get home. Otherwise, I would do as you suggest. Just do not feel like postponing vacation 21 hours to save a lil headache around Chicago.Just plan on leaving Ft. Wayne about 3 or 4 am. Traffic will be light and you can zip right through whatever route you want to.
Fast, with guns blazing... and if you don't like guns, there's a cinematic guide called "The Blues Brothers." Just don't **** off anyone in Ohio or country music singers.
Going through to Janesville, WI and points west or north, this is the route I normally take.

I have tried continuing into Illinois on US-30, and it is not a good idea.
I can see some advantages to taking I-80 to I-39, but it takes you a good distance south before you head north; I dislike the back-tracking and taking the right angle instead of the hypotenuse by following the preferred route. I also take Bigtanker's advice and leave very early to avoid the traffic on I-290/294.
Safe journey.
