Possible, but these are also the type of aircraft you would expect to see in mass during any naval conflict or blockading action against China. I believe the PLAAF/PLAN are working on their version of Rapid Dragon.
Relatively slow, but plentiful, cargo planes, would be a pretty obvious choice for launching a saturation attack against USN or Japanese forces operating outside the range of their land based missiles. Again, assuming they develop a similar system to Rapid Dragon.
