Could I configure High Availability between FG-201E and FG-200E?

I'm planning to utilize my existing FG-201E as the active and FG-200E as the standby. Will this be possible? If yes could I deploy these two in Active-Active scenario? Will appreciate inputs from your end. Thank you! :)

No. It's not possible.

I believe you can only set up VRRP to achieve some level of failover and failback. The hardware and licensing needs to be identical for fortigate HA clustering.
