Yes, I had something like this in mind. However, IIRC the PIOs can only operate as fast as the ARM cores, correct? So, if my understanding is right, a large chunk of clock cycles would be wasted waiting for instructions and data to arrive over the serial link itself rather than actually executing them. Not to mention, the core on the other end of the link would probably want some data back, and that would take even more clock cycles to send over.
the only real solution there, is to design your software around that limitation

have some kind of computation that takes longer to compute, and send a few commands over the link, so it always has something in the queue to work on
