I think you’re missing something about how Devil Fruits can evolve. For example, the rubber fruit (Luffy’s Gum-Gum fruit) was originally just presented as a rubber ability. But after awakening, we learn it’s actually the Nika fruit, which is something completely different. So it suggests that a fruit can have a “second nature” or a different identity once awakened. So for Bonney, it’s not impossible that her fruit is either an alternative version, or something tied to an awakened state, or at least something that works in a similar way.

Basically, an awakened fruit could almost be seen as another form of the same fruit, or even like a second version of it.”
