In the NAB cup, maybe. It won't be happening in the regular season though. They will feel no need to try something that they already know will not work. Playing 5 ruck/forwards with the shortest of them being Hawkins would be footballs equivalent of suicide IMO.
I reckon the last few years we've seen some teams picked that have left us all a little confused, hence why I will not be surprised to see it happen during the H&A. Over the years, the coach has commented that they've tried players/set ups at times to see how they go. Not saying I necessarily endorse this approach, however, that is why I believe we may see this.
