1) if your transformer is only 7.2VA, you won’t be able to run activate two zones at the same time — if you do so, the transformer voltage will drop very rapidly and the valves will reset.
2) I don’t recommend wiring two transformers in parallel, especially since different transformers have slightly different output voltages, and I don’t know what would be the consequence if you connect them in parallel.
