I'll give your idea a shot one of these days.
As what I mentioned earlier, it is still achievable in a single photo (without blending, PP) by boosting up a much higher ISO to shorten the shutter speed, the main purpose of the blending technique is just I able to have a better image quality with lower noise level.
Another way you can do is to use a light painting technique, it helps to brighten the foreground and the person with faster shutter speed without the need to boost up the ISO. Below photo is done in a single shot but of course, you need to help from friend
