Not completely disagreeing with you but... trying to convert the sheer sophistication of those fight into gameplay would be very costly.
And we are not talking of going full Open-world crazy.
Most of the ground battle are small squad battle, rarely giant battleground unless you are crying goodbye to a beloved medic.
If you want to involve spaceship you either make a whole spacefighter minigame, or you fight inside the corridors or a giant space.

Stargate setting is pretty bad for large battle with a constant stream of cannon fodder. It can also barely afford vehicular gameplay.

And I played the Half-life mod for Stargate.
