As it turned out, mithrillium not only allows to stabilize the enchating process and make it more predictable, but with some resonators attached, I might be able to select exactly what I need. Additional bonus of this all is xp-free enchanting! All I need now is only some essentia nearby. To start the process one's going to need to select all desired enchantments and activate the Shadow Enchanter with Caster's Gauntlet.
