Thanks, everyone, for all this great insight
I've been practicing at the Whistler learning area a lot lately and my one footed skating is getting better. Still nervous that my back foot will slide off and twist my knee or ankle. So I've been ever so gradually trying skating on slightly steeper grades at the learning area and trying J turns.
I had a near epic upon unloading from the chair yesterday. A crowd of skiers was standing in the offload area. When I got off the chair I literally had no where to go. I can steer - slightly - with one foot in now but there was no way I could avoid the skiers. So I just yelled - nicely - at them to move and put out my hands. Fortunately, I didn't knock anyone over.
Putting pressure on the stomp pad and against the back binding helps. But sometimes the board pivots and then the toe side edge catches and my back foot pops off. This still worries me because of potential injury. I'll do what folks here have suggested and keep practicing one footed.
