I don't know if this will throw off the balance of the game or make it sweeter.
The idea is that you can carry one or two or three weapons/drones/models/etc in your inventory as you level up, during the battle, you can switch to that weapon when needed but that will take up one move.

As for visual effect, the weapon can be shown on the back of the opponent mech and inspected.

What do you think?

I do not think this is a workable solution and it would make game play less enjoyable.

Part of the game is the unknown and making your choices before battle then doing what you need to win. Also it is making adjustments in between battle to make a winning combination to beat those you meet online.

There have been nights where I have faced the same guy 4 or 6 times out of ten battles and making adjustments in between has taking me from losing the battles to winning. This could mean switching out weapons of one type to another to overcome a resistance, or switching mods or kits.
