The GPL doesn't import arcpy, nor use any proprietary code.
I think the question you have to ask here is this: does your plugin require arcpy to function properly (whether via a bridge or not)? If it doesn't work without it, then its a derivative work*... and since it obviously doesn't work without pyqgis, which is gpl, it can't legally be released as is.
