FortiGate 200F capacity

Hello everyone
In my company, I have two 200F FG. One for branch office, one for HQ. HQ and Branch are so close so I want to maybe connect two sites physically in one server room. I would like to use 200F as HA Active Passive mode but I am not sure about the performance. Here is why:

If I use one FortiGate as active, it will have the traffic from Core switch that connectes to two distribution switch + 8 access switches in total. For subnets, I have currently 10 subnets each on FG, 18 FW policies each

Do you think that I could achieve to use FG 200F for all this traffic? there is no server or internal routing. Just pure internet connection :)
