Yes, BBL and breast augmentation can be performed simultaneously in properly selected patients, although it can pose a bit of a challenge in the healing process. Most surgeons recommend patients offload the surgical sites with some activity restrictions. Since the breasts are in front and the buttock in back, it is hard to simultaneously protect both areas with positional offloading in the early postop period. Additionally, simultaneous procedures add to the anesthesia time, so it is important to review this with any surgeon with whom you consult. We like to keep operative times to 6 hours or less, which is very doable for the combination you are proposing, but if you start talking about a breast lift, tummy tuck or other add-ons, it may be better to stage procedures.
