I have removed, rebent/modified re-installed my front swaybar. Noticible improvement in the corners, much more level. I basically bent a curve in the middle of the bar which reduces the flex of the swaybar and keeps the front end much more level in the corners. Removing the rear will only cause more instability, and it actually causes UNDERSTEER, not oversteer. Stronger swaybar front or weaker rear causes understeer. Weaker front/stronger rear causes oversteer.
I prefer a bit of understeer for snow driving, especially with rear wheel drive that can conpensate. I can fly around in 2wd on snow and not worry about oversteering to the point of loosing it. I can swerve back and fourth at 50+ on snow and IF traction is lost, it's only on the front tires and I stay straight. I feel completely comfortable doing this, even with the 3" lift. Around slower corners slight understeer allows for better control drifting...way safer and more fun.

I normally run w/o rear swaybar when Offroad for more flex, and with the front stiffened my body roll ON road w/o the rear is still not bad at all. I would run only front, except I would imagine more even tire wear with both on rather than just the front.
I also run E load rating tires with stiffer sidewalls for better handling. I autocross my 97 corvette (not the jeep because it's a jeep...lol), but I don't like my SUV to handle like a boat either. I still enjoy spirited driving in the corners w/ my Jeep and accelerating out of them.
FYI you can still get bigger wheels/lower profile tires with an all terrain off road tread that would significantly improve handling, but then you would risk scraping the wheels more on rocks with less tire. Not worth it in my opinion.
