If there was even a powered and unpowered AEC, as they occasionally only ran in 2-car sets, we could fill in a centre coach with many options. 

Agreed. One of the design challenges for IRM would be how to configure DCC features. Their integrated one-chip system on the Electrostars and ICRs is very clever and ideal for a fixed-formation train, but doesn’t suit the AECs which could run in many different formations with a variety of intermediates. The model coaches would need to be through-wired for that approach to work. 
If I were to make my own, then I’d have a power and a dummy car and perhaps put a chip in each.
