Good news for you: The Brits picked up the idea, and have developed it as Brimstone
Bad news for you: The Russians also picked up on it, and have fielded it as the supersonic 9M114 Ataka/Sturm launcher/missile, with a range of 6KM, now being extended to 10KM. Fitted to light personnel carriers or obsolete tank chassis with their turrets removed, they can make armor operations very costly.

Now that's a little known episode. The French did us all a big favor when they kicked Qadaffi's butt down in Chad. He was not going to stop there--Libyan agents were arrested in Mauritania and even Nigeria. But his army was whipped so badly in Chad, he lost all his military mojo in northern Africa. His Army never again was a factor. Didn't know about the Mk-19s, though. Thanks.
I recall an 82nd Airborne experiment of the late 1970s known as Slammer VI, essentially the mounting of six rocket pods from attack helicopters onto an M151A1 Jeep. The idea was to offer the airborne something with a capability beyond that of their 81mm mortars, if not that of a 155 SP battery, thereby freeing up the Airborne's helo-delivered 105mm Light Guns- or for those instances when they weren't available via helo delivery, or were needed for direct fire missions.
The Artillery folks at Ft Sill found out about it and were horrified: with 17-pound warheads, the setup put more steel on target than either the 81mm or 105 could deliver, nearly equalling the cannon's capability, and not only cheapbeyond belief, but using assets already organic to the airborne and light divisions. It became a threatr to the careers of those pushing the then-yet-untried MLRS system, and so was killed by orders from on high.
But now, there are terminal guidance warhead systems like the Army APKWS available for the HYDRA-70/2.75 inch rocket, a sort of *poor man's Hellfire*....And if it works off an Apache helo, it ought to work off a Jeep or Humvee....
