No, no and NO!
I HATE the rest mechanic, because this just adds unnecessary complexity and is breaking the flow of the game all the time, it's extremely annoying and doesn't contribute to the fun of the game.
Since this is a video game, it should be as smooth as possible, and the resting mechanic is a pure PITA. Drop it for good.
It's a D&D game. It's balanced with that mechanic existing. There are tweaks which could be made, which is what we're discussing, but it you remove it, the balance will get even more out of whack.
