If you mean you have a bridge officer with the creativity trait, I would expect it would apply to their ground powers. Kits and BO powers are the same thing, just differently implemented. For a captain, you get your powers through your kit, but BOs get the same powers through their 4 ground abilities.
There are benefits to doing it this way. As a captain, you could swap kits and try out different powers easier than you can change a BOs abilities. For team play, you could carry multiple kits and use the one that best suits the team you are currently in.
