And i doubt their small numbers would like to be launched 3-4 kilometres away inside a crate

Its actually surprisingly difficult to get non-powerup's to launch from an armoury succesfully. High-speed is a must, because otherwise most of youre objects will crash into cliff sides or get dragged accross the top of buildings. The Service and Speeder crates in my variant for example, and Steeveeo's nukes, have to be launched at high speed, or they will get sucked back down to the ground.
Haven't quite figured out why that is yet, something to do with collision meshes. Try placing an SRV missile launcher right in the corner closest to the enemy in hilo, majority of the time, the nuke WILL hit the terrain, and result in framerate munching base death.
Therefore, scion crate lifts are out of the question
