Eh, I'm okay wih masers.
Also, you can let your SoD level be a bit higher in a robot setting, yeah, but logic can still be a thing here, this is closer to a Real Robot setting than it is to a SR one.
Also note, I grew up with Voltron as an initiation to the mecha genre, and I loved watching GGG. I just don't think this is the place to go that way.
I've toyed with the idea of running a more Super Robot Vs. The World style quest a few times. It'd have Finishing Attacks, exotic powers sources like Courage or Magic, Hotblooded pilots and possibly a more structured Research system because I feel that while the "You can research everything! Sorta" approach is nice and allows a lot of freedom for us, but it could use a way to tell the players whether something is viable, or if our technology level allows what we want to be built.
Sort of a simple research tree where you use research actions to unlock things like "Directed Energy Weaponry (Tier 1)" and "Exotic Power-plants" which would then allow you to research how to build the Lightning Shotgun and cheaper Nuclear Vortex Reactors and also unlock "DEW Tier 2", "Ultracompact Reactors" and "REALLY Exotic Power-plants".
So now that you have the Tier 2 DEW... Let's call it "Theory", you can build a Better Lightning Shotgun with a very low research DC, or a basic Laser or Maser cannon, but that one needs to be hooked up to the Jaeger's reactor to fire at full power. Then the "Ultracompact Reactor" comes in and allows you to build it without that drawback or let you supercharge it by using both the gun's reactor and the Jaeger's together.
Of course, "REALLY Exotic Power-plants" lets you build Supercell reactors or the other weird stuff like using Magical Energies to power your Super Jaeger.
It would complicate things, yeah, but it gives the players more direction in what they can or can't feasibly research at the moment, hint at what sort of crazy things they can get in the future and it would allow the same amount of freedom we have right now, because the QM just needs to judge what sort of rough requirements the player's idea would have and then it could be added to the Research list. And you'd still be able to research weapons and armor you don't have the requirements for, it'd just be more difficult and the research into the item would still count towards obtaining the "Theory" requirements.
Of course, I wouldn't be able to run a quest like that because, for starters, I'd need to figure out a new system to do justice to the sort of crazy shenanigans Super Robot Shows have, either by expanding this one or by making one from scratch. Then there's the fact I'm a lazy bum who can't write regularly to save my own life.
