OK- First off... half one color, and the rest of the jeep, another color will get old quick- guaranteed. You will wind up disappointed if the entire jeep doesn't flow from front to back completely...no matter what colors you use. It will simply look unbalanced and strange.
Although many people (including yourself) love the thought of the olive drab...I would not take the extra time and trouble to do it (at least not right now). You are kind of a perfectionist, and right now you have a lot of other variables to consider...( recovery, possible future health concerns, expecting new family member, getting back to work, and many other mods that you are planning).
You have accomplished a large part of this "rear corner" project already. You have strengthened the corners, chopped the frame-rails, added the perfectly located receiver hitch, and added in LED flush-mounted tail & back-up lights.
If you were in a different situation- then I would say go for the olive drab, but I KNOW there are other pending modifications and non jeep related things that you will soon be occupied with. If you simply finish off the red in the primered locations, then you will be more satisfied to move on to other projects. The jeep's color is not going to be the determining factor on your happiness of it. Your performance upgrades will. You will be much more satisfied with a red jeep that has the axles, gears, steering, shocks, etc...the way that you want...no matter what the color is.
Finish those corners in red and move on. Down the road, if you are just itching for some thing to do, it will be almost as easy to strip off all the red and repaint it all at once.
