In case you still read this: Occasionally I am doing the same with old HDR Projects, or when I have to rely on the backup recording on an MDR if my main recorder failed.
I use a little USB to Lian LI device that served me well but I guess your FW dock does the same. HDR Files are timestamped so you can easily spot them to the right place in Protools. Because the HDR made the 15min break in files sometimes it is a bit of work to spot everything onto the right track but it works. In Protools you can select the timeline drop order so you could spot all files of one track seamlessly in one go.
I used to go the FTP route years ago but today it seems that's technology from another century which indeed it is
Good Luck!
