Well, anything is possible.
I don't know if I've ever seen it done, but the intelligent key (as far as I can tell) is just active RFID. If there were a way you could mimmick that RFID signal, you could just wire the RFID transmitter to something that only got power once you did the remote starter.
Probably not the answer you wanted to hear though. Again, I'm not sure if anyone even makes that.
