Modular internal upgrades for weapons, thrusters and other external blocks

Something that's always bothered me in space engineers 1 is how the amount of weapons/thrust you can have in any particular direction is directly related to the surface area available to mount these exposed modules. This disadvantages larger ships which have lower surface area per volume, unless you're willing to go for a wall of thrust or weapons which doesn't usually look good or realistic, creating scaling problems and encouraging walls of weapons even on smaller designs since more firepower tends to win fights.

A good way to get around this would be to allow upgrading weapons and thrusters with modular systems, similar to how you can attach efficiency modules and whatnot to refineries and assemblers in SE1. These modules can be mounted on the back of a weapon or thruster to increase its effectiveness in various ways, reducing the need to spam more on the outer hull.

A few suggestions for possible upgrades:

-Propellant compressors to increase maximum fuel consumption and thrust

-Magnetic propellant accelerators to increase fuel efficiency

-Autoloaders to increase rate of fire of weapons systems

-Recoil absorbers to increase accuracy during sustained fire

-Barrel coil attachments to increase muzzle velocity of weapons

-Cooling systems to increase maximum power consumption of energy weapons such as railguns, coilguns and lasers (if any of those are added to se2)

In my opinion all modules should function just fine without any upgrades, but when increasing the scale of your ships the most sensible upgrade path should always be to upgrade modules over spamming more, with multiple modules of the same type only being necessary for redundancy's sake in most cases.
