Longer axle (from a fat bike?) and a hack like the @Hulsroy thru axle front rack?

Yes it does, it’s a special axle that comes with the trailer. Not sure how to budge that, but two rear panniers could make up for the trailer... but is that much stuff really necessary?
If she can have tent and sleeping equipment. You should be able to fit the rest into two large panniers. Front or rear.
I use a tag along trailer, in combination with a kid and front panniers. It means I carry almost everything. It’s pretty heavy, but riding is very predictable and I can even handle it on smaller trails without a problem.
I’m very happy with it.
