Perhaps. You will have to test it out. I suspect you may need to include inrush current limiting. Essentially, you use a SPDT relay’s NC contact to introduce a drop resistor in series with the primary winding. This reduces the inrush current (energising current). Then, when the secondary reaches a minimum voltage (say 12V) it turns the relay on which connects mains to the primary winding through the NO contact…

I will publish this modification soon….I reckon it would be handy to have inrush limiting….
