I'm guessing that using a newly emptied Jameson bottle won't work either? I'm just about to start bottling my Pecan Pie Porter and I think i'm going to be a couple bottles short.
I just finished a bottle of Jameson while I was prepping my bottling space and I was thinking about filling it with primed porter, but I would hate for it to explode.
I might just fill it anyways and put it inside a bucket with a lid, and see what happens to it. If it explodes it will be mildly entertaining (assuming i'm drunk when I find it) and if it doesn't, it will be something I didn't know before.
If i'm really lucky, it might add an interesting flavor to the porter since it has a little bit of Jameson left in the bottom.
