Biggest problems are weight (that CRC bag weighs 8.6kg without anything in it) and support (if you were to just add wheels/pucks then the bag will sag around those high points and rip as you drag it).
Using your own wheels is interesting but airlines will make you deflate before flying and you will still need to support the load in some way.
GSport link is probably the easiest way to do it.
