Would it not be easier to replace SSH with something more modern that actually exposes that as a feature? I've been thinking about that the past couple of years, with today's building blocks an SSH alternative is so easy to build. I bet if you guys were to build or back such a system it would be the right quality and get the adoption it needs. Opaque SSH sessions are such a thorn in my side.
