For the life of me I am unable to remember the make but, in the mid 80's there was a company making a 'sidecar' on which the wheel used to lean with the bike. It was used to get around the learner restrictions for solos.
They also started to make small mono-trailers for bikes, tried one on the rear of an FJ600 and you really couldn't tell it was there.
Not for me but, I understand where you are coming from.
I also understand the replies you're getting as the SX really, IMO, is more sporty than that type of bike. (I would also say that my old 1250 Bandit was a far better tourer
