LT8708 with GaN FET or SiC

Hello,

My customer use LT8708 & LT8708-1 in their system.

And they are trying to modify around circuit of LT8708 & LT8708-1.

At this modifying  design, they are reviewing to use GaN FEC or SiC.

( Applied points are M1 ~ M4.)

Would you confirm the usability of GaN FEC or SiC with LT8708 ?

Please advise me.

Regards,
