Talk to your gm & gaming group, and expect to spend a lot of fate points. That's not something that I, as a gm, would allow in potion form - but I'm not the one running your game, so whether I'd allow what you want is mostly irrelevant.
However, saying "I wouldn't let you do that" isn't really helpful, so here's an alternative notion:
Leave a potion slot empty - at which point, a regular old lore declaration can fill it in with whatever you need to bypass the current foe's defenses. Need fire to hurt the ice drake? Sure, lore declaration (difficulty 2), and you had already prepared an oil that creates a "flaming blade" aspect when applied to a sword. Need inherited silver to hurt a loup-garou? Sure, lore declaration (difficulty 7), and you've got a prepared mixture of inherited silver dissolved into a liquid form and enchanted to be usable as a weapon coating. And so on.
