How about putting motorized wheels on trailer rather than bike (trike)?
Also, if heavy should have brakes. Those could be controlled with a lever from the bike, or could be "surge brakes" which apply if it tries to overtake you.
The motor control could be a lever on the bike. Or, could be a servo in the hitch (similar idea to surge brakes.) If bike pulls on hitch, it powers its motors to follow and reduce force on hitch.
"Deal on batteries" - many people here get LiFePO4 cells in the 280 Ah range. But other lithium batteries from EV (used) can be even cheaper and less weight for same kWh. To use such batteries you need a BMS that works well with it.
