This spliting of ability scores was done in AD&D 2nd Editon in the Players Option: Skills and Powers book.
And boy, was it open to abuse...
Strength: Stamina, Muscle
Stamina: Weight allowance.
Muscle: attack, damage, open doors, bend bars, max press.
Dexterity: Aim, Balance
Somewhat balanced... Aim: Ranged attacks. Balance: AC, I think surprise.
Constitution: Health, Fitness
Health: System shock, Resurrection survival (I might be wrong on one of these).
Fitness: hp.
Intelligence: Reason, Knowledge
Reason: Some wizard-only stuff.
Knowledge: Some other wizard-only stuff and proficiencies.
Wisdom: Intuition, Willpower
Intuition: Cleric spellcasting stuff.
Willpower: Saves vs. magic.
Charisma: Leadership, Appearance
Leadership: Henchmen stuff.
Appearance: Reaction modifier.
For many of these, it was sort of a no-brainer which one to increase at the expense of the other (Fitness, Knowledge, Willpower). Also, given the way you needed high stats in 2e to get any benefit, they were very easy to manipulate ("Oh, I rolled a 14 for Con. That's no extra hp, and system shock 88%. I guess I'll increase Fitness to 16 and drop Health to 12, for +2 hp and SS 80% instead.")
