Friend, You are correct in your concerns about seat height when hunting out of a pop-up blind. The Pacseat sits a lot lower to the ground and causes some problems with shooting in some situations that you will encounter.
The 360 on the other hand has adjustable seat height from 16" to 22" and with the individual adjustable legs will sit level on uneven ground, it will get you high or low enough to shoot out of the blind no matter what the terrain.
In situations where I want to use my 360 and I have a long walk in, I use an old fleece fieldline backpack that weighs almost nothing to take my 360 into the hunting woods. As far as getting busted because of the height of the stool/chair? I guess I'm not following you? All I know is, the height of your seat will and does make a difference when hunting out of a pop-up blind.
