How to Randomize Looted or Crafted Item Quality with Perk?

[Subject4056]

I would like to somewhat randomize the quality of items produced by crafting, such that higher levels of a crafting skill would lead to higher levels of crafted items on average, but any given craft would not be deterministic. I know that CraftingTier will do this deterministically, this is not what I want.

 

I have looked into loot quality templates and items with the OpenLootBundle action, but I cannot find any example of a perk influencing loot lists directly rather than just re-weighting the items in a lootgroup.

 

Is it possible to achieve what I'm trying to do with just XML modification?
