The two straps that attach the Carradice bag to the saddle will need to be re-threaded and buckled up each time you remove and re-attach the bag, so it's probably not the most convenient choice for your usage. I remember seeing quick-release systems for these bags, but you'll have to check if they work for the massive Camper version. There is no actual handle either, but I suppose you could rig one up between the two straps.
