I think it would be cool to just make spell-slot/long-rest-ability recovery cost inspiration points. Those points can then be refilled at temples/shrines/inns via "donations". Solving quests awards inspiration points. Obviousy those points can only be spent outside of combat.
Being downed in combat incurs fatigue, fatigue can only be restored by resting. Likewise you can only consume a limited number of food between rests to restore health. Fatigue in turn decreases movement pointss/acrobatics/athletics.
Resting in itself does not recover spell slots, but costs rations. During rests you can either heal or recover a very limited number of inspiration points. Story-related rests do not cost rations and can be triggered by talking to the relevant companion.
That way you decouple health recovery from spell-slot recovery which imho is the crux on why resting is so difficult to balance. It also gives more control for "world-building" spells such speak-to animals/dead and the like.
Resting as is works fine for vanilla DnD where the DM can regulate the flow of the game, for a video game I feel as if more granularity is needed IMHO.
All this could be conveniently explained into the DND rule-set with the tadpoles.
Bonus: add some flavor items which restore a number of inspiration points. Different companions like different items.
Double-Bonus: Resting slowly resets vendor attitude. Vendor attitude increases by buying items from the vendor.
Tripple-Bonus: Some quests are timed and resting gradually reduces inspiration/money earned.
