This armor set doesn't have to be top tier to begin with, actually it shouldn't. It should be craftable around Nanosuit level tech. At it's core it IS a shell after all, you just install more complex components. With full installation, it could definitely trump Quantum though, but at a REDICULOUS cost, past Quantum itself.
My proposal doesn't add any extra items, so no pressure on your spriters. I'll try to explain why I chose these parts in the first place, too.
Here are my suggestions for the Gregtech recipes for the armor itself:
The Tinkering Table is similar to yours, but uses advanced circuits and a Computer Monitor (for display and interface):
The helmet, and pretty much the entire suit, uses aluminum as a lightweight and modular base for attaching components, machine parts for moving joints/connections to other parts of the suit, and a Data Storage Circuit for storing tinkering and overclocking information. The helmet also uses a computer monitor to act as an internal visor for interface with the outside world and showing the status of the rest of the suit, EU levels etc.
The chestplate is just an aluminum shell, again, with a control circuit for storing information:
The pants are similar to the chestplate:
So are the boots:
I chose these parts because they're not that hard to get, but aren't attainable after you make your first batbox.. 4 Data Storage Circuits are used, which require 8 Emeralds since you get 4 circuits per craft (9 with the Table).
Aluminum is a medium tier metal in Gregtech as well.
Armor upgrade components:
Firstly, instead of (5) Iron and (5) Diamond plating, it should be (4) Titanium/(3) Iridium Plate/Energy Shield as the 3. (I love that energy shield)
The capacitors are as follows, in order of LV, MV, and HV:
The LV uses just Refined Iron, wiring, and 2 Lithium Batteries (You can also use Energy Crystals)
The MV uses two Lapotron crystals, Titanium, and wiring.
The HV uses two Lapotronic Energy Orbs (8 lapotrons each) and Chrome ingots. I feel this one might be a bit too hard, though.. Might bump it down to one orb.
Wiring is crafted as follows:
Uninsulated copper and Silver ingots (It should craft around 3)
The solenoid is made of wiring and Steel ingots (for a good ferromagnetic conductor):
The servo motor is crafted using Brass ingots, Steel ingots, two advanced circuits, and a solenoid.
I chose these parts because Brass is a good bearing material, and when attached to the solenoid's steel shaft would act as a low friction connection between the steel housing and the brass shaft. The circuits are there to provide pulse-width modulated energy flow for adjustable speeds to the rotor.
The parachute is crafted using Carbon Fiber Plates, wool, string, and a Nitrogen cell:
The Nitrogen cell is used for a high pressure quick ejection of the parachute (that's why it can deploy so fast!) and the carbon plates are to house the wool and gas canister.
These are all low-mid tier resources.
The Glider wing is made from Magnalium plates, a Carbon Fiber plate, a solenoid, and an Advanced Circuit.
Magnalium is a mid-tier resource in Gregtech. It displays a very high strength to weight ratio, being extremely lightweight for it's strength. These plates are attached to a Carbon Fiber plate for stability and integrity, and is also the housing of the Advanced Circuit, who's job is to interface with the chestplate's data circuit for quick deploying of the wings themselves.
Now, for the big guns. I find flying to be an extremely high tier ability, and thus this recipe will reflect my reasoning.
The Ion Thrusters are almost alien in technology, exhibiting very high speed and power thrust. They're made from HV capacitors, Iridium plates, a superconductor, Iridium Neutron Reflectors, and advanced heat vents.
This would craft ONE thruster.
The Iridium plates are for integrity and stability (this is a hell of a device). The superconductor is required for the vast amounts of energy flowing from the armor to the HV capicator. This capacitor discharges its energy in constant high speed pulsed bursts, which are directed and reflected from the Iridium Neutron Reflectors, which bump into each other at almost light speed inside of the thruster, and are ejected out of the advanced heat vents, which provide an extremely powerful burst of directed momentum.
