Trim the boot slightly ?
I have already (after I took this pic), but even the smaller rib diameter is still a little loose. If there’s no way to otherwise clamp a normal fork boot to the slider, I suppose this modification is better than nothing.
A fork brace is an excellent addition, especially if it’s on a sidecar.
Indeed—the stock brace would almost certainly be tested like a wishbone on Thanksgiving.
The NTX brakes are however already woefully bad on a solo machine

Besides, since it’s on the V7, I just decided to use the V7’s twin pot Brembo and make a brake caliper adaptor to bridge the mount-to-disc difference, which I’ve figured to be around 3mm. Initially started cutting out of aluminum block, but ultimately decided to go a simpler route with some 3mm thick steel plate sandwiching the stock mounts, like in my drawing below:
