What do you think is is the minimum wind speed required to enable me to simply body drag, practice flying / handling the kite (85kg, 11m kite) at Melville water?
Most kites will fly at 10 knots, some way lower if in consistent winds. If you can launch it and keep it up, you can always learn more things about how your kite flies. Try picking a spot on the edge of the wind window and see how fast you can get the kite there. Try holding the kite steady on the edge of the window at a low height (~1m). Try moving the kite from left to right while not moving your feet at all. Then do it again with your feet together. Then fly it faster. Try flying the kite while not looking at it. All these help you understand what your kite is doing and how much power it can deliver.
Body drags take hardly any additional power once your kite is flying, so only another knot or 2 and you should be able to practice them. I'm about 250 hours in and still fine tuning body drags so don't think it's wasted effort.
Another little hint is to body drag with your board in front of you held out by your leading arm so that you're almost lying on the board. Use the board to cut in like you're riding it and you should be able to go waay upwind like that. You can use this to make up ground from you're last dash and splash, or simply get into a comfortable position away from the shore to take your time setting up to go. It also helps with getting your bearings on what angle to the wind is possible once you're standing up on the board.

Or am I better off just packing it all away until spring?
Nope, that won't achieve anything for your kiting. It might make it easier to plan other areas of your life, but having a mad keen desire to get a kite up in the air if there's enough wind is up is the best way to keep progressing.
