I have two phases, one much shorter than the other, but it looks like I have to make the transcription the same for both- same number of nodes and polynomial order for each one, other wise I get a numpy mismatched array size / broadcasting error. Is there a way around this?
Do linked OpenMDAO phases in a trajectory need to have the same transcription?

You do not need to have the same transcription for both.
Here is an example of setting up a very simple cannonball problem with two phases. The first phase is Radau, the second phase is GaussLabotto. Both use the same ODE, but different orders, numbers of segments, and compression setting.
