Megavvolt, G'day.
I (first) started thinning the plate that is welded to the fork by cutting a shallow arc shaped groove in it, where the disk hub was rubbing. I used a grinding wheel on a Dremel tool and I did it carefully by degrees but being such a light metal, I didn't want to thin it out too much, so I then reverted to shaving a couple of mm off the hub where the screwholes are, unfortunately. It wasn't a new hub so I didn't mind sacrificing it.
I suggest getting a basic front hub for the wheel for the trailer, unless of course you can afford to sacrifice the disk hub that you have. There is no way that I can fit/screw the brake disk onto the hub that I modified. I reprimed and repainted the fork, where I cut the shallow channel.
It might be possible to use washers as spacers to help spread the fork so that you don't need to modify the hub. I couldn't find washers, at the time, that had the right internal diameter and external diameter. It might be worth taking the wheel with the quick release, to a specialty fasteners supplier, to see if you can get the exact size washers to use as spreaders. If you can find washers to use as spacers, you might have to shave a flat edged side on the washers' circumference so that they fit where the dropout is welded to the fork. I hope that that makes sense?
Another option could be getting some spacers machined if there is an engineering shop in your area or do it yourself, of course, if you have the tools. As you have no doubt noticed, the Extrawheel fork is far from rigid.
