But there should be no problem with the Travoy, because it mounts to the seat post, or so it seems
I've pulled my kids' two seater WIKE trailer on my Brompton. It works! But it's awkward... not my first choice... if I'm bringing that large of a trailer, it's not exactly travel friendly, so I might as well just as use a larger bike. Your mileage with the Travoy or other similar system might be better.
