This is pretty close to final.

But I don't think your final tweak is optimal. Starting from the above, I begin by making the I-80 counties be the northern edge of the Southeast district by moving Jasper and Iowa Counties to the Southeast and Jones and Jackson to the Northeast. Then to balance it out, the Southeast cedes Lucas to the West and then either the West cedes Worth to the Northeast or exchanges Hardin for Mitchell depending upon whether lower deviation or keeping I-35 north of Des Moines all in the West is considered more important.
