There are only a VERY short list of possible candidates that would be shooting "stealthy anti-ship missiles" at China's carrier strike groups seeing as how the only producer is the US and the only users are the US and their closest puppets (pretty much only Japan and ROK might get involved, and Philippines hosting US forces but not directly fighting). And it just so happens that all of those candidates host US bases that would be struck by ballistic missiles anyways at the earliest sign of mobilization and war activities spotted by Chinese satellites. If your suggestion is that China would sit back and allow itself to be struck by hundreds of missiles without retaliating, then you're entertaining delusions.
B52s and B1Bs are easy for China to spot and shoot down and the US has very limited numbers of B2s which hold very limited payloads. Trying to wage an air war based out of Hawaii is not going to get very far given the very limited cadence for air operations, limited primarily by the small numbers of B2s.
The transport of heavy weapons to Taiwan are completely unnecessary and even pointless. All the destruction of military infrastructure and equipment on Taiwan will occur from Chinese missile superiority given the very short distance at play but also their air superiority over Taiwan's air space, and so merchant ships would only need to bring drones and special forces. The distance at play is so short that China only needs to use SRBMs to hit Taiwan, while longer range missiles are preserved for US bases, forces, and puppets.
