I took a stab at converting ReadxAODHybrid.py to CA, and it seemed pretty easy to get a working job.
The good news:

Not so good (maybe):

If we want to have both plain xAOD read and Hybrid mode, can that just be an argument to the function rather than a separate function or file? And do any of the services set up here seem obviously unnecessary?
