An other option would be to utilize a buck boost transformer, MUCH cheaper, less heat gain, less exciatrion current loses and smaller foot print.

Very practical to overcome low voltage, once again you would need to arrive at an average safe voltage between no load VD and full load VD, that is acceptable to your use.
