2 Post Lift Suggestions

What you can do, if you must, is lift the car a foot, then use jackstands to hold it up while you lower the lift then add risers. If you do that properly, you can gain enough added clearance under the vehicle to walk freely, jump, or even force the vehicle through the ceiling.
The best “accessory” I ever bought for my 2 post is a set of race ramp wheel stands. They are very strong while being super lite. Let’s you use a 2 post for front end would be an easy quick stopping point for doing what you just laid out to get some extra height when lifting a car...will probably end up doing that when I change the coolant on the viper this fall so I get out of the way of an antifreeze shower.
