Can the full-bridge be paralleled?

I am designing a full-bridge control. 12v/50a.  It's looking like current mode control with a current doubler circuit.  My client asked if these bridges could be paralleled. I am looking at the LTC1922 & LTC3722 parts. Any input would be helpful.

Thank you.

    Hi

    I would recommend the LTC3722 with the LTC3901, and yes, the converters can be paralleled. I would use an ideal diode on the output of each converter to prevent negative current issues, the LT8672 would serve. Here is a general circuit that can be adapted for current sharing.
