Turns out they liked the idea, and that's why i'm posting this on a Anet watched forum now. =)
The idea is to make weapons, focus items and shields that are not inscribable inscribable for a set fee, customizing them to your character.
I was told this would probably crash the market, because 'crappy' blue and purple items would just be made inscribable.
I've thought of a catch, make the 'make inscribable' option available for Rare (gold) items only, and the 'inherent mod' disappears after making it inscribable, to prevent high rate inscriptions being pulled from low grade weapons.
It could be done at a weapons smith, giving a second option next to customizing, something like 'Customize and Inscribe'
Thank you for your time.
