Actually, just having the main controller MCU on the secondary side that directly pulses the main FET with the optocoupler could work, provided you get your bootstrap MCU power supply right and optocouplers could be made to fire fast enough. Like pic related but probably with a totem-pole between the opto+pulldown and the main FET.
