I was thinking mostly One Year War stuff, where cannons/lasers are the predominant ranged weapons.
Although I had great success in a campaign with a starship which used funnels as a point defence system.
Anything that closed in got hit by upwards of 64 remote controlled drones firing rapid-fire laser cannons.
But you're right, this is more Xabungle/Dougram/Front Mission style.
The next priority is writing rules for aircraft, to my mind. Making more mech sheets is time-consuming more than hard, but aircraft will need different rules.
I'm thinking they'll work like normal units, but there will be new "keywords" associated with them like "anti-air" and "air to surface" which counteract vertical range penalties.
Aircraft in the "stock setting" will be high-tech Ace Combat style ones, armed with nasty missile launchers and energy weapons alongside machine guns and cannons.
You could quite easily rework these rules into a Gundam wargame if you wanted, though. Funnels would be a low-damage weapon with a high Accuracy and Armour Piercing/Multiple Hits (6) or something - expensive, but deadly.
