Diamantine to plasteel conversion mechanic please

[Flawless]

I suggested this solution a while ago (march).
Basically, quality upgrades (with rng/slot machine) should cost only plasteel.
Anything else (customization with 100% player agency) should cost only diamantine.

Both currencies would basically stay useful until you have a perfect version of all items.

@Flawless

• ability to pick Perks from a catalogue (implemented in Patch#12)
  (like Reblessing, small cost every time a Perk is swapped)
• ability to permanently remove locks from Perk/Blessing slots
  (2k Diamantine per lock; removing the 2nd lock could be more expensive)
• ability to upgrade weapon modifiers (allow everything to go up to 80 or 100)
  price it something like
  → 100 Diamantine per 1% increase per modifier until 80%
  → 150 Diamantine per 1% increase per modifier 81-90%
  → 200 Diamantine per 1% increase per modifier 91-100%
• ability to unlock a Blessing of choice for the library
  (5k Diamantine for T4)

There goes our diamantine.
Ressource imbalance, endgame and everything regarding itemization, solved at the same time.

Got excess diamantine? Spend it on the systems i mentioned above.
Improve the good items that you already have, or save up to buy that specific T4 blessing that you want to use, but could not get your hands on.

Got excess plasteel? Upgrade grey items.
Maybe you pop out an item that is better than what you currently have.
Maybe you pop out a new T4 blessing that you do not yet have.
(The diamantine cost for quality upgrades could potentially be lowered or removed to make a more clear distinction between quality upgrades and customization.)

Also, it would be nice to get some plasteel and diamantine when salvaging items.
This would allow us to also convert dockets to plasteel/diamantine via brunt.
