Weren't there some plans for a jet to surround the rocket and have a common exhaust? Not quite a tractor rocket but perhaps enough to limit blast effects?

I have often thought about "jacketed" thrust streams where colder exhausts buffer nozzles from a hotter, inner-core stream...

I'm not aware of any, but that doesn't mean they don't exist.

That's usually done to increase total mass flow, as a ducted rocket.
