Not that easy I fear. The trouble is that as seen by your example you’d like to navigate to a page in the pop-up that is also Aurelia enhanced. So essentially the bootstrap/enhance needs to happen there as well.
Take a look here for perhaps a few more inputs How to open and syncronize a pop-up window?
Is there a reason this has to be a window pop-up? From the name I expect this to be a report, perhaps a PDF file or such. Could you describe your use case?
