New Vendor Recipe : Multiple Essence Crafting

In your opinion, will it be useful/enjoyable to have a new vendor recipe using multiple essence ?

The system could be this way :

You trade at a vendor one base item (normal rarity) and multiple essence of different kind to guarantee mods contained in which essences. You could add up to six different essences to get a rare with desired mods. The resulting item will have the mods contained in the essences traded, and other random mods (or not, RNG :)).

The requirement will stay the same (ilvl of the base item, mods added will depend of the item type (body armor, ring, boots, etc). This onyl work with a base item with normal rarity, so you would still have to use essences directly on item to get the "chaos orb" effect of high rank essences.

It won't kill trading/crafting/RNG because some mods are unobtainable on some item base with only essences, e.g. +X% elemental resist on rings. And as you use multiple essences once, i don't think it would make essences less valuable.

They intentionally made essences ignore master meta mods for the sole purpose of making sure one item could never have more than 1 essence mod. I can't imagine they would add that back in. And if they ever did, it would be at a cost of the exalts that a master charges for enabling such crafting.
