Hmm. That makes a good deal of sense. The only issue that arises is if you have either a stingy or generous DM as far as short rests go. I personally am a little sketched out by the idea that my power comes from every time I take a short breather. Would it be comparable to make it the same number of them, just on a per day basis instead of a per rest basis? ex at level 8 you just have all 6 slots from the start of the day instead of refreshing after a rest. Does that imbalance the class terribly?

Either way, I'm pretty set on playing this for our upcoming campaign, I'll be sure to report back on how it performs alongside the other characters.
