Gooday Bloggs, I fear this will attract some of the ANTI ADSB brigade, but in short yes the trikes and drifters and Jabiru's and Savannah's can power a small radio, and can also power the ADSB out unit. There is no valid reason why not. Some may have reasons but none valid.
As for the aircraft type mix, they all can work together OK....it takes airmanship and following the rules. For the RPT folk who really do need an extra layer of protection due to fare paying pax and their speed and size, ADSB in, or at least TCAS and 100% Mode C is really all you need.
The unicom is probably a great help to them as I have observed. We just need some RPT drivers like yourself who operate into YHBA or anywhere else there is a trial Unicom and plenty of RPT/RFDS/GA/RAA traffic to add some useful comments.
