I appreciate the feedback. The main driver for the quick jack is I already had it in the garage so I figured I should make use of it. I use the quick jack a ton for my other cars and they are great in a small garage.
I've gotten it together now and it turns out it works pretty well.
Originally, I was going to fix the extensions for the jacks to the table but it was a pain in the ass. It works great and is plenty stable without fixing them and the future flexibility to move them, level them, change to something shorter or taller is great.
The legs in the four corners with wheels create about 1/10th inch gap in the center of the table but when the jacks are in place it is completely flat.
I ended up with 10" inboard legs for the extensions and ~13" legs for the outside (8' 4"x4" post). With some basic wheels from harbor freight.
