I'm thinking a bit clearer this morning, switching the second toroid across the AC output is no different than switching a huge Toriod Variac cross the existing inverter, very big current surge and half the time tripping the inverter with over 600A Peak DC input surge.
I'm assuming that having around 20R in series as a pre-degauss substantially reduces the inrush current on stage one.
When starting the inverter wired as a full dual power stage inverter, it should be no different than starting it as a single stage inverter, as both toriods would be soft started together from zero.
