As a FATE fan I also wanted 5e Inspiration to work more like FATE points rewording the Personality Traits to be more like Aspects. Such Aspects can be use to help in Tragedy play
eg some Aspects for
Heathcliff (Wuthering Heights) - Brooding, Vengeful Romantic
Ideal -
"What is mine is mine forever!"
Bond - "The moors are my refuge - and my cage!"
Quirk - "Haunted by Love, Consumed by Hate"
eg
Romeo - Stupid boy in love
I - "Love is the only thing worth living for"
B - "nothing will separate me from my true love"
Q - "I follow my heart, consequence be damned!"
eg
Stradh von Zarovich - Vampire Lord of Barovia
I - "I was wronged, and fate will regret it."
B - "My name will be remembered, and my rule will endure for eternity"
Q - "I wait in the darkness, I brood - what else is there for me?"
If these example characters were PCs it would be up to the player to play up the traits (with Inspiration points as the incentive) - it will need a really skilled DM and PC buy in, the OP establishes that PCs are up for it. Having a stress mechanic would be good too
I suggest you play Dungeons of FATE
