As @appleblossom said, you cannot enter the US as a visitor with the intent to stay and adjust status. In addition, even 1 day being out of status (if that happened) would prevent you from ever adjusting status from F2b category. "Out of status" would not be forgiven. See the USCIS guidance below. I would absolutely wait and go the consular processing route.
