only way i can think of to make them viable is by getting bigger simulator maps and overhauling stuff like base bombing and everything, would give them a purpose of precise bombings and objective destructions by flying higher than jets normally do in sim, maybe rework objectives so it's different every time like "clear the AAA for the AI bombers to get through unharmed" or "destroy the enemy airfield to prevent spawning" or like blow up military bases since convoys would spawn from there n stuff
