Jetpack/Backpack Modularity

I have thought of an incredible idea for SE2: adding functionally different suits and jetpacks/backpacks.

First, all these suit and pack options can be changed at a block called the armoury, like the SE1 block, but it has functionality this time.

Second, different types of jet/backpacks that can hold different modules. There could be a cylindrical module slot that can hold gas bottles (H2 or O2), liquid bottles (liquefied H2O), a voltage amplifier that boosts tool speed/performance in exchange for lower power efficiency, a gas compressor that boost jetpack boost force or siphons O2 from low atmosphere environments, a hydro-turbine (high efficiency and power under water propulsion but disables suit thrusters), or a pack-mounted H2/O2 generator or basic assembler (packs start with this in classic survival but could swap it for a different module later). A rectangular type of module slot could hold modules like power cells for increased suit power storage capacity, storage modules (some come preinstalled), internal atmospheric conditioning (IAC, comes pre-installed; stay inside and you can remove this module without consequence, incompatible with non-airtight suits), or heavy-duty transmitters/scanners that boost your range. The standard pack contains one cylinder module slot with the basic assembler and four rectangular module slots with two storage modules, an IAC module, and a heavy-duty transmitter. Other packs may contain a different configuration of module slots that make the character lighter or heavier, affecting their walking speed, inertia, gravitational influence and fall damage.

Third, different helmet types like: TI (thermal imaging), binocular(/zoom), sonar, pilot's visor (provides target-locking visual, target data (name, mass, faction)), and an anti-radiation mask (reduces radiation exposure by 30% of total environmental radiation), and you could also not wear a helmet. As well as different suit torso pieces like: reinforced armour (reduces weapon damage to the wearer and also makes them heavier), anti-radiation torso piece (reduces radiation exposure by 35% of total environmental radiation), and a formal suit (a two-piece suit emblazoned with a faction symbol). And different boots/pants, including: armoured boots (further reduces weapon damage to the wearer and also makes them heavier), anti-radiation boots (reduces radiation exposure by 30% of total environmental radiation), mag-boots, and formal pants (plus shoes).
