Premium gun repairs system at extra price

[primal sorrel]

It would be cool to have Premium Service when it comes to gun repairs, it would bring back the gun to 100% but at extra high cost calculated as:

• the cost of all parts together but as + 25% to the price of parts already unlocked at vendors and +50% to of parts that are not unlocked at vendors yet (regular long time repair);
• the cost of all parts together but + 50% to the price of parts already unlocked at vendors and +100% to of parts that are not unlocked at vendors yet (fast repair);

Or if it's too easy, then:

• the cost of all parts together but + 50% to the price of parts already unlocked at vendors and +100% to of parts that are not unlocked at vendors yet (regular long time repair);
• the cost of all parts together but + 100% to the price of parts already unlocked at vendors and +200% to of parts that are not unlocked at vendors yet (fast repair);

Not sure how it would play in a long term for game balance/difficulty, so give me what you got and let's see what everybody thinks.
Cheers!

I'd like to have the cost be lowered for an extremely long repair time (12ish hours) so I don't have to spend the cost of the gun to repair it, especially if I found something that I don't have the rep to unlock

maybe an "overseas repair" that takes a long time (like I said, 12ish hours) that doesn't have a price increase for parts that haven't been unlocked?

I don't know...
12 hours is a long time for someone who plays every day for long. It's no time for someone playing a few times a week. How to make it hard for those who play rarely?

If it takes long, especially because it has parts from overseas, the high price feels even more justified.
I don't feel like importing genuine quality parts from afar to an island where transport is difficult and fuel at shortage should be cheaper - it kind of makes no sense from economical point of view, if you will.

I assumed this would already be a premium since it's a full, 100% repair

if you want to do these sort of things, especially weapon maintenance, it's a lot easier to ship the whole gun out, have someone repair it where they have an entire workshop and tools available to them, and ship it back versus a quick repair in, for this instance, some former rich person's backyard underneath a tarp in the jungle
