I used to make this call but hated gambling this early for my whole stack in a likely coinflip scenario. I also used to make a standard pfr with AK in the early stages and often check fold to a non A or K flop but I started to hate this also. So lately I have been limp/calling average sized raises preflop with AK and checkraising/raising the continuation bet when an A or K flops and folding when it doesnt. My whole motive is to minimize the number of chips lost in the early stages. Not sure if this is a good strategy though.
