I recently got an idea for an SCP that would be a drug (maybe a device) whose effects would be essentially based on Dr. Jekyll and Mr. Hyde. While I have got what I think are some fairly solid ideas (more realistic mechanism of action, lack of outward physical changes, some backstory), the fact that it's still so close to something from classic literature makes me wonder if it's at all doable. Thus, I ask: If it were sufficiently well-done, would something like this be possibly decent as an SCP, or does its relation to an existing story make it a non-starter?
For reference, what I've got so far:
-The drug doesn't actually cause any changes to a person's appearance
-The drug, when active, increases activity in parts of the brain relating to altruism, empathy, and forethought/impulse control, while depressing activity in areas related to violence and/or strong emotion, and suppressing testosterone production (reducing sex drive in both men and women, among other effects)
-As the drug wears off, there's a rebound/backlash/withdrawal effect that's largely the reverse of the drug's effect
-The drug is addictive
-It came to Foundation attention after a member of the team developing it started secretly dosing her preteen daughter, causing her to behave exceptionally well while she was at school and in public, but leading to progressively more severe rebounds at home, eventually leading to the researcher's murder at the hands of her daughter.
