Sorry for my bad English, it's not my native language. I would like to propose the following:

Every player has his/her own favourite style of making progress through the game. So as everyone has commonly used boosts. So why don't devs make for us smth like "Alchemy Forge" where we could turn, for example three less-used boosts, into one better boost of another quality and rarity. Here are some examples of my imagination - new icon on the top, the ability to add chosen boosts to the forge and the forge itself.
