I was thinking if it's possible to make a station that would have a weapon input, allow you to choose elemental types ( mod types included maybe), and then accordingly to the level and rarity ask for a certain quantity of the item of said element. For instance: applying poison to a lv1 common assault rifle to require 2 venom samples, while applying it to a lv6 legendary weapon would require about 40 or more.

Maybe even tiered elemental types! LV1 flames, LV2 flames... so that they'd be even more useful and play a bigger role in the game ( plus neat visual effects? :D ).
