Thought I should post back - the film made it here and I have already split two 100ft rolls off of one 400ft pack.
I sourced a small piece of plywood from a local DIY store and drove two 100mm long and relatively thick nails through it. On one nail goes the 400 roll and on the other the center core for the 100ft roll (thanks Ned for sending them!). Below the core I placed a cardboard cutout that is the exact size I need to fit into my loader so I can feel the gap between it and the film and know when to cut the film.
Here are some pictures of the process, it went rather smooth but it took me 30 minutes of continuous winding which left my right arm numb for a period of time thereafter.
The 400 reel is very stable and was easy to take out of the plastic bag and place on the plywood. The end of the film is taped with a rather long piece of tape that I ended up sticking on my left arm so I can retrieve it when putting it back away. I also cut small pieces off of that tape to use for the smaller 100ft rolls I made.
Just to be on the safe side I did this in my darkroom which isn't 100% dark but good enough for wet printing. Thought it'd be better should I need to remove my hand(s) from the darkbag for whatever reason. 30 minutes is a long time without hands

1600ft of magic looks like this:
The plywood and the nails:
Here you'll see all what I used, the darkbag and the plywood with the two nails driven through it. You see the little cardboard cutout I made and the center core on the right hand side nail. I also had gloves (which are surprisingly hard to wear if you don't see your hands!!!). I used the gloves when spooling the roll onto the core but had to take them off for attaching the film into the core - for that I needed to feel my fingertips to be precise. As I loaded two 100ft rolls I also had another tin canister which isn't shown on the picture. The first one I loaded I left open in the darkbag so I'd know which of the two it was. The 2nd one was closed with the core and black plastic bag inside it.
And finally the finished product - two tins of 100ft film sealed and ready to be used.
