Yes, this is very doable. PIX4Dmapper is camera agnostic so it can processing imagery from your Nikon or any DSLR for that matter. As for the GPS dongle, if it writes the data directly to the image exif then there is nothing more you need to do. However, often you may have a CSV file that contains the GPS and orientation data. If this is the case then you can import the file along with the images and Mapper will read the corresponding data. It is a very straightforward process. I think the most difficult parameter to maintain will be your image overlap since I assume you will be triggering the camera manually.
Interesting problem. My initial thoughts are to compare this flight to a manual flight with a drone. I know of several cases where users flew a drone manually but set the shutter to capture images at regular intervals. Essentially every 2-3 seconds an image was captured. If the drone was flown steady then the overlap could be somewhat maintained.
So, if you know your camera parameters, flight height, and flight speed then you should be able to calculate how often the shutter needs to be triggered. It is a bit of a complex math problem but I think you have enough of the variables to make your calculations. The article below can help you perform some of the calculations.
