Sure can as long as the load on the 200 amp panel isn't over capacity. 112kva will handle way more than the main panel. Why are you using such a large trany with only a 100 amp breaker

Only a load calculation will tell you.
If there's a highway to hell and only a stairway to heaven, that pretty much tells you what the traffic patterns are expected to be.
