I'm not certain that the rules allow that...maybe, maybe not. It's not clearly defined. You should talk to your local FSDO and see if you can get the OK for something like that before you do it. If you just show up for a checkride with night sim time, I doubt any DPE would perform the checkride without federal clarification.
Another thought...the FAR's actually have provisions for earning certificates without night flying time. This is because it doesn't get dark in northern alaska in the summer! I don't have a FAR/AIM handy but look that up. IIRC you get a ticket that is limited to daytime-only until you accomplish the night stuff (which you would probably just never get around to). You would have to go to Alaska though.
