Possibly, but the only way I know how to make potions in RM is through alchemical spells, and he doesn't have spells.
He's a Scholar, so his spell list cost is merely 4. I'd suggest the GM to create a quest for his group, where the goal is search for some ancient lore and power, to which the Scholar can access. In game terms, the Arcane Coven spell list "
Brewing Lore" allows the creation a lot of different potions, including ones embedded with a spell. Since it's an Arcane spell, according to the RoCo. I, a "non-spell user (may use) one spell pick to learn every 2 levels of an Arcane list; i.e., 1-2, 3-4, 5-6, etc. Each spell after level 10 requires a separate pick to learn", so the rules actually allow a Scholar to learn spells from the list, up to level 50. As for being an Arcane Coven spell list, well, Arcane Covens are supposed to be highly secret, ancient, mysterious and all the usual stuff, societies, so I'd say searching for some of their hidden knowledge fits an adventure for a Scholar (and his friends).
Or course, it's up to the GM to customize the above part, but the rules allow them, so he only needs the flavor text— I mean, the story going with them.
…technically, Indiana Jones is a scholar! Since he's a college professor! :p
