Floating Ground
I'm not sure how to float the ground in Spice. Maybe Eric or someone with more knowledge of it can help.
You can download most devices for LT Spice. The trick is to find the model you want and then learning how to do it. I downloaded the high voltage transistors because I was worried about their leakage current. They will need a small heatsink.
Q1 is current limit. It turns off the pass transistor if the current gets to high.
It is still not clear to me what you are trying to accomplish so I'm not sure I am on the correct path.
All of these are self contained. I'm not sure that works for you.
