I would like a system where instead of alchemical energy to craft a trinket, you combined a trinket with a certain item to get a specific trinket with a 100% chance. It would not only provide another use to currently underused items, it would also add some level of consistency to runs. It would probably be a good idea to leave the current random recipe in place though, as an alternate option so you still have a chance of getting the trinket you want even if you can’t get the corresponding item for whatever reason.
