Hut Bagging in the Bogong High Plains Area

I'm planning a trip for the end of next year for a club walk. I've done the AAWT 2 and a bit times so wanted something different. Planning on a couple of circuits without too much doubling up but there are some areas where local/previous knowledge is needed or I could just wing it (haha).
I'm going along the AAWT, from Mt Hotham, as far as Ropers Hut. Then I want to get to Cleve Cole Hut but was going to go via the Timms Spur trail, bagging Cairn Creek Hut and over Mt Bogong.
Question 1- anyone gone done the Duane Spur to Big River and followed the river up to the Cairn Creek Hut? This could be something different.
Question 2 - What's the camping like at the Cairn Creek Hut for up to 8 tents?
Then I will continue along the AAWT from Cleve Cole to Mt Wills. From MT Wills I'm leaving the AAWT and heading down to where the 107 track joins the Paton Track. The obvious way would be to backtrack 5kms and go down the Kangaroo Creek Track but on Google Earth I notice that there are a couple of tracks that appear to run south, down the big spur lines, off the AAWT south of Mt Wills where the AAWT turns East before hitting the Omeo Hwy. This would allow me to put in a food cache near the Omeo Hwy.
Question 3 - anyone have any info on these tracks, not marked anywhere?
Question 4 - Is Paton track open to 4x4's, as I will need to get a cache in somewhere if I opt for the route down Kangaroo Creek Track? I know I can always walk them in.
From Youngs Hut I plan to walk to the the Brandy Creek firetrail and then follow it up to the main road and along to Dinner Plains, visiting JB Hut on the way.
Question 5 - Is the Brandy Mine worth a visit?
Thanks in advance.
