One could build more sophisticated ramp infrastructure (like Manhattan’s tunnel approaches) to better handle traffic flow, but it’s really about optimizing the neighborhood and pedestrian experience.
What expressway anywhere has on- and off-ramps every block? The merging and lane changes required probably just create congestion. Generally speaking, the less choice you give drivers in where to go (one-ways, fewer lanes, segregating traffic lanes by ultimate destination with barriers), the smoother traffic flows.

What you suggest would be nice but I'm thinking there would be a LOT of pushback especially since the Circle and Kennedy ramps will have all been rebuilt in the last 10 years. That was the time to plan for such a major change I'd think.
Realistically what I think is more likely and feasible is to cover the portions where you don't have to work your way around ramps. Such as between Wayman/Fulton, Fulton/Lake, Jackson/Van Buren and maybe Halsted/Peoria, Peoria/Morgan along the Ike. Start there and if deemed successful maybe there would be less resistance towards finishing the rest of the trenches along the Kennedy later.
