If ice doming is a big concern consider moving a diffuser closer to shore as noted by esshup. Diffuser 20 ft from shore would likely allow air to vent at the shoreline. Something to try.

I think with your severe winter conditions a pump spray technique would result in a massive frozen ice sculpture. Likely more trouble that benefit. It could work if the pond did not receive extended weeks of 0F temps.
