Nah, I don't like it. Here's why:
1. The whole point of getting a secret in the first place is to re-connect a mechanical thing with the fiction. Adding more mechanical things to that fiction seems a bit much, like it runs counter to the point, or it's just too ornate. I feel like if you need more mechanical incentives, you're probably not making the fiction compelling enough in the first place.
2. Too many +1s all over the place. I mean, yeah, I use them in custom moves sometimes, but they really do clutter up the game. What's the point in having stats if you don't just use them as they are? Hx resets to +1, use it at +1, that's still pretty good odds. The xp for reincorporation is better, but there's really only a good/bad dichotomy here: if the other player says something cool it doesn't really need to be incentivized, but if they say something lame then you're possibly incentivizing the reincorporation of something lame. And trying to keep track of what bonuses you have to upcoming rolls can get in the way of keeping track of what's going on in the fiction.
Maybe it works for you, I dunno, but those are my thoughts.
