100% agree with.@UselessTriviaMan If you want ideas on Inspiration rather search through the AngryDM's site for his post on Inspiration. He incorporates Personalities Bonds, Flaws etc into it integrating the two rather well.
As for your other idea I use something different for that, but we have similarities. Experience Points relate to the character, while Plot Points relate to the player.
Plot points are earned for being punctual (1 point), writing up an obsidian portal wiki post (4 points), hosting (2 point), catering (3 points), creating tokens..etc (2 point) or maintaining ones character sheet (3 points).
Plot points are lost at a rate of 1 for every 5 minutes one is late for a session.
Plot points may be used on PCs and NPCs - for Plot Armour [1] (damage prevention 1 point = 2 damage prevented), Add Plot Element [5] (advantage/disadvantage, temporarily ignore wound penalty, temporarily ignore environmental affect), the Plot Thickens [11] (add minor detail to story, upgrade miss to a hit or hit to critical, downgrade critical to hit or hit to miss), A Plot within a Plot [15 points] (add major detail to story).
Unused Plot Points at the end of a session may be traded in for XP (1 Plot Point = 250XP). We use different XP tables, slower rate of leveling.
